1. A prominent investor who holds a large stake in the Burton Tool company has recently claimed that the company is mismanaged, citing as evidence the companyfs failure to slow production in response to a recent rise in its inventory of finished products. It is doubtful whether an investorfs sniping at management can ever be anything other than counterproductive, but in this case it is clearly not justified. It is true that an increased inventory of finished products often indicates that production is outstripping demand, but in Burtonfs case it indicates no such thing. Rather, the increase in inventory is entirely attributable to products that have already been assigned to orders received from customers.
In the argument given, the two boldfaced portions play which of the following roles?

A, the first states the position that the argument as a whole opposes; the second provides evidence to undermine the support for the position being opposed;
B, the first states the position that the argument as a whole opposes; the second is evidence that has been used to support the position being opposed.
C, the first states the position that the argument as a whole opposes; the second states the conclusion of the argument as a whole;
D, The first is evidence that has been used to support a position that the argument as a whole opposes; the second provides information to undermine the force of that evidence;
E. The first is evidence that has been used to support a position that the argument as a whole opposes; the second states the conclusion of the argument as a whole;

2. Gortland has long been narrowly self-sufficient in both grain and meat. However, as per capita income in Gortland has risen toward the world average, per capita consumption of meat has also risen toward the world average, and it takes several pounds of grain to produce one pound of meat. Therefore, since per capita income continues to rise, whereas domestic grain production will not increase, Gortland will soon have to import either grain or meat or both.
Which of the following is an assumption on which the argument depends?
(A) The total acreage devoted to grain production in Gortland will not decrease substantially.
(B) The population of Gortland has remained relatively constant during the country's years of growing prosperity.
(C) The per capita consumption of meat in Gortland is roughly the same across all income levels.
(D) In Gortland, neither meat nor grain is subject to government price controls.
(E) People in Gortland who increase their consumption of meat will not radically decrease their consumption of grain.

3. Business Consultant: some corporations shun the use of executive titles because they fear that the use of titles indicating position in the corporation tends to inhibit communication up and down the corporate hierarchy. Since an executive who uses a title is treated with more respect by outsiders, however, use of a title can facilitate an executive's dealings with external businesses. The obvious compromise is for these executives to use their corporate titles externally but not internally, since even if it is widely known that the corporation's executives use executive titles outside their organization, this knowledge does not by itself inhibit communication within the corporation.
In the consultant's reasoning, the two portions in boldface play which of the following roles?
A. The first presents an obstacle to achieving a certain goal; the second presents a reason for considering that goal to be undesirable. B. The first is a consideration that has led to the adoption of a certain strategy; the second presents a reason against adopting that strategy. C. The first describes a concern that the consultant dismisses as insignificant; the second is a consideration that serves as the basis for that dismissal. D. The first is a belief for which the consultant offers support; the second is part of that support.E. The first is a belief against which evidence is offered; the second is part of the evidence offered against that belief.

4. Astronomer: Observations of the Shoemaker-Levi comet on its collision course with Jupiter showed that the comet broke into fragments before entering Jupiter's atmosphere in 1994, but they did not show how big those fragments were. Nevertheless, some indication of their size can be inferred from spectrographic analyses of Jupiter's outer atmosphere. After the fragments' entry, these analyses revealed unprecedented traces of sulfur. The fragments themselves almost certainly contained no sulfur, but astronomers believe that the cloud layer below Jupiter's outer atmosphere does contain sulfur. Since sulfur would have seeped into the outer atmosphere if comet fragments had penetrated this cloud layer, it is likely that some of the fragments were at least large enough to have passed through Jupiter's outer atmosphere without being burned up.
In the astronomer's argument, the two portions in boldface play which of the following roles?

A: The first is a claim that the astronomer seeks to show is true; the second acknowledges a consideration that weighs against the truth of that claim. B: The first is a claim that the astronomer seeks to show is true; the second provides evidence in support of the truth of that claim. C: The first and the second are each considerations advanced in support of the conclusion of the argument. D: The first provides evidence in support of the conclusion of the argument; the second is that conclusion. E: The first is a circumstance for which the astronomer seeks to provide an explanation; the second acknowledges a consideration that weighs against the explanation provided by the astronomer.

5. The United States minted about 857 million silver-colored gSusan B. Anthonyh dollars between 1979 and 1981, but the coin proved unpopular because it looked and felt too much like a quarter.

A. The United States minted about 857 million silver-colored gSusan B. Anthonyh dollars between 1979 and 1981, but the coin
B. About 857 million silver-colored gSusan B. Anthonyh dollars were minted as coins in the United States between 1979 and 1981 but
C. About 857 million silver-colored gSusan B. Anthonyh dollars that were minted between 1979 and 1981 in the United States
D. About 857 million silver-colored gSusan B. Anthonyh dollars that the United States minted between 1979 and 1981
E. Between 1979 and 1981 the United States minted about 857 million silver-colored gSusan B. Anthonyh dollars, which

6. Critics of certain pollution-control regulations have claimed that the money spent over the last decade in order to reduce emissions of carbon monoxide and of volatile organic compounds has been wasted. The evidence they offer in support of this claim might appear compelling: despite the money spent, annual emissions of these pollutants have been increasing steadily. This evidence is far from adequate, however, since over the last decade a substantial number of new industrial facilities that emit these pollutants have been built.
In the reasoning given, the two portions in boldface play which of the following roles?
A. The first identifies a claim that the reasoning seeks to show is false; the second is evidence that has been cited by others in support of that claim.
B. The first identifies a claim that the reasoning seeks to show is false; the second is a position for which the reasoning seeks to provide support.
C. The first is a position that the reasoning contends is inadequately supported by the evidence; the second is a position for which the reasoning seeks to provide support.
D. The first is a position that the reasoning contends is inadequately supported by the evidence; the second is evidence used to support the reasoningfs contention.
E. The first is a position that the reasoning contends is inadequately supported by the evidence; the second is evidence that has been used to support that position.

7. In countries where automobile insurance includes compensation for whiplash injuries sustained in automobile accidents, reports of having suffered such injuries are twice as frequent as they are in countries where whiplash is not covered. Some commentators have argued, correctly, that since there is presently no objective test for whiplash, spurious reports of whiplash injuries cannot be readily identified. These commentators are, however, wrong to draw the further conclusion that in the countries with the higher rates of reported whiplash injuries, half of the reported cases are spurious: clearly, in countries where automobile insurance does not include compensation for whiplash, people often have little incentive to report whiplash injuries that they actually have suffered.
In the argument given, the two boldfaced portions play which of the following roles?

A. The first is a finding whose accuracy is evaluated in the argument; the second is an intermediate conclusion drawn to support the judgment reached by the argument on the accuracy of that finding.
B. The first is a finding whose accuracy is evaluated in the argument; the second is evidence that has been used to challenge the accuracy of that finding.
C. The first is a finding whose implications are at issue in the argument; the second is an intermediate conclusion that has been used to support a conclusion that the argument criticizes.
D. The first is a claim that the argument disputes; the second is a narrower claim that the argument accepts.
E. The first is a claim that has been used to support a conclusion that the argument accepts; the second is that conclusion.

8.

11. Investment banks often have conflicting roles. They sometimes act for a client company by raising capital from other investment institutions as advantageously as possible, but their analysts also sometimes send unfavorable reports on the financial health of companies for whom they are raising capital to other clients who wish to make investments. Analyses of companies' financial health need to be unbiased if an investment bank is to achieve long-term success.
If the statements above are true, which of the following practices, if adopted by an investment bank, would hinder its long-term success?

A. Evaluating and rewarding the bank's analysts on the basis of recommendations made by managers who are solely engaged in raising capital for clients B. Using reports by the investment bank's analysts to determine how best to raise capital for a client C. Sharing the task of raising capital for a client with other investment banksD. Ensuring that conflicts between analysts and those who raise capital for clients are carefully mediated and resolved by impartial arbitrators E. Monitoring the success or failure of analysts' current predictions about how companies will perform financially, in order to determine the value of future predictions

Some 32 schools have run any experimental class, each school two classes, altogether have invited 37 teachers. These 37 teachers each person at least must bring a class, most belts three classes. Asked such speech, simultaneously led three classes' teachers, its quantity has the possibility the maximum value and the minimum value. Option A.0 and 13, B.0 and 14 C. 1 and 10..... At that time has chosen B, afterwards as soon as thought, should be A: ( 284. Also met quite several to ask the approximate value the topic, for instance the 9^9-9^2 approximate value was: A.9^9 B.9^8 C.9^7.... The such similar topic appeared three in the different time, my corona ~ 285. A factory always production cost distribution like cake chart shows (in the cake chart each part of costs is 40,,000; 20,,000; 20,,000; 10,,000; 10,,000). Said they product manager decided each part of costs all proposed p percent comes, to compose a new product the cost X, asked P the expression the result which (with X expression) I does is X*10^ (-5) (the present super sleepy, topic approximately is this, if has in any digital question, everybody has a look mentality to be good, regret) Which does 286.9^8-9^2 most approach with? Several options approximately are 9^8 9^10 9^13 9^6 9^11 287. Below which and r, s, is the t standard difference same i) r-2, s-2, t-2 ii) 0, r-s, t-s iii) t-1, r+5, s-4 288. Last year beginning of the year stored 40,000 first year interest rates is a r% each quarter finally 日计rest time asks r =? 1) this January 1 interest income was smaller than a (true definite value to be concrete is how many seriously records) 2) last April 1 balance of account is 1,200 Yuan 289.3J6 and 6KM are two three figures, they and were equal to N0J3 (four figures) ask K the value 290. The person which has a, the person which the b two matters makes the person which a is person's 2 times which b only makes b is which ab all is person's 1/2 ab all does to have 2500 to ask only makes a to have how many people 291.0 0; L in x axis 截距 x formula) 307.9feet×12feet asked used the option which how many brick bats I met to be as follows 1) 36inch square and 72inch the square two kind of specifications 2) square 6×6 and 12×6 (inch) looked at topic very many, was allowed to confirm in this option was said the brick bat was a square shape 308. Meets together JJ, is in a that package installs AB ONLY, in a package installs BC ONLY, and so on, the answer is 64, definitely 309.a/b +b/a =2, asked the essential condition, chooses a-b=0 to affirm 310.A, the B two places have two roads, is away from S, another distance is long 30, a person speed each hour is N, another quick 15, asked if long colored time compared to first few, little how many! This writes my very corona, has chosen A, M51 is not said this topic was right 311.70 meters ladders and wall included angle 60, takeoff 7 meters, asked how many the ladder apex to the ground distance is? The answer is 42 How many 312.7×0.000001/0.00007 is equal to? 10^ (-11) 313. Person's monthly salary every year September 1 change, asked this year monthly salary how many (1) 17,000 (2) last year average wages was 15,000 chooses C in July 1 to December 1 average wages 314. The topic is said some person must travel, she estimated distance is X kilometer, estimated the airplane speed is y kilometer/hour, then asked the error is within 0.5 hour. 1) the distance error is the within 5 kilometers; 2) the speed error is the within 10 kilometers/hours. I elect am E, may distinguish supposition distance the value and the speed value, then may figure out the error to have is bigger than 0.5 hour, also has is smaller than. The estimate was calculates rightly, because the next topic was not specially simple. 315. Asked a what thing does heat up, changes the warm speed to use Ces? ? Degree measures the speech, is rises 0.5 Ces? ? Degree per minute, asked expresses the speech with F degree, the per hour speed is how many. Produces 90 F degree the change to be equal to one of 50 Ces? ? Degree. The option remembered has C 33 E108 other not to remember, has done for a long time, I look like elect am C, then the estimate was does mistakenly, because behind that topic very simple. 316. Some as soon as writes DS, produces X company the female staff member and the Y Corporation's female staff member's proportion is 1: 2, asked X company male staff members and female staff member whether is more equal than with the Y Corporation's male staff member and the female staff member? 1) X company's male staff members compared to the Y Corporation's female staff member's proportion are 1: 4; 2) the Y Corporation's male staff member and the Y Corporation's female staff member's ratio is 1: 1 (probably, did not remember was several ratios several). I elect am C 317. (Last), which establishment does a/b+b/a=1, ask the following: A, a-b=0 B, a+b=0 C, the a^2+b^2=1... answer is A. 318.a and b respectively are (348.656789 million) the ^2 units place and 十位数, asked following who does establish 1, a=1 2, b=2, 3, b=4 A, 1 only, B, 2 only C 1 and 2 D 1 and 3 answers are C (order possibly have difference). Some several were on JJ already has, is not redundant. Has the together feeling quite to be strange, is the bird flies lake that road. 319. Bird's average velocity is 18 meters each second, asked the lake is not the width is smaller than 21KM. (1), the bird used not to fly to 20 minutes (2), the bird has used not to 0.4 hour. I elect is E. Because 20 minutes birds may fly 21.6 kilometers, is unable to know the accurate result. At that time but felt the topic asked is very strange, perhaps there had the problem. 320.if K+P is odd, then what must be even a) K-P b) K+P+2 c) k+3p 321.square perimeter 2, area=? 322.7520 power, unit digit? 323.A:B:C=9:4:5; B 7 A+B+C=? A) A+c 0? 1) mp+st 0 2) mt+sp 0 I have chosen c 337. A sum of money, the annual interest rate 10%, asked three years interest many are less than two years interest? Under 338. numbers (6x) is not integer 1) x/6 is integer 2) x/600 is integer 339. In the coordinates for 3 o'clock said is in a lake 3 islands, asks the straight line to walk a length, and said on the chart a unit is actual 1mile, three distances extract are under the 5+5+5* root number (2), asks the approximate value 340.x^2+y^2=1, asks x+y=1? 1) xy=0; 2) y=0 341. In order to dredge the wharf, needs to dig the 5000*87*10 cube the silt, part needs to put to 43,500 trash fields (landfill) goes, under asked this trash field tolerates 100分之 several silt. 342.DS topic: L and the M two straight lines, ask slope that big? 1) L to X axis point of intersection is, the M axis and X axis point of intersection is negative, 2) two coarse threads intersections in Y axis ortho-axis. This writes me to estimate was does mistakenly, because I did not know the slope did have the positive and negative division, therefore has chosen E. Hoped everybody can pay attention. 343. [ (X1-X2)/(X1+X2) ] ^2, the datum is X1=1.4*X2, asks the result, is an approximate value. 344. (99,999-1) ^2 may express is? The answer looks like is 10^5* (10^5-2) 345.

Some 2 experimental curriculum teaches (altogether 64 halls) in 32 schools, altogether some 37 teachers, the condition is each teacher at least teaches 1 hall, does many may teach 3 halls, asked teaches 3 halls classes teacher's smallest possible population and the most greatly possible population is how many, my answer is B (0 and 14) but looks like (0 and 13) is more correct, at that time was the corona. 347.N is a positive integer, also N eliminates by 3, Yu Shu is 2, asked N^x+2N is not by 3 contains? 1) x=3; 2) N=5; Looks like chooses a, because the first condition I have tried many numerals, all can by 3 contains. 348. The formula (X@Y) = (X+2) ^2+ (Y+3) ^2, asks T the value? 1) T@2=74; 2) 3@T=80. should solve two equations to be able to obtain. I am feared two equations the solutions solve not together, therefore all has tied, T=5. 349. A vehicle, the original cost is 0.251 kilometer, then the oil price rose 12%, asked runs 350 kilometers to have to consume how many charge for oil. 350. D S topic: Is correct the topic is said some person ＄ 2.5 has bought n stock by each, then first time has sold m, second time has sold n - m, asked second time sells, each stock price? (1) n = 2 m (2) second time sells, altogether has sold ＄ 22,400. This wrote me to think a meeting, chose E, the reason on has not been able to extract the concrete value. 351. P S topic: X = 0.01, asks (1 - x 4 powers)/(1 - x) value? This wrote me to start directly x to substitute, has wasted a time, should be first 约分, then figured out that formula with x expression, then substituted x, was allowed with ease to obtain the answer. 352. Also has together writes is that trapezoid, 60, 59, 61 that topics, because has 3 3 angular side, with is big to the big angle method, first separately in first 2 3 angular center (from left to right order) side confirmed the size relations, then substitute the 3rd triangle, the careful spot, cannot be wrong. 353. Said some integer X eliminates take 13 business as a Yu Shuwei 2, eliminates take 17 numbers also as 2, asked a eliminates take 17 numbers as how many. 354. Has met that topic classics arrangement automobile topic, is P5,5/P3,3 that 355. Sits the title, a irregular similar circle east east, the topic said is a lake side, inscribes a triangle, tells you three apexes the coordinates, asks this lake the area Must look at the answer according to the option Figures out this triangle the area is 17. 5, then this irregular east east area should be 17.5 again is smaller than east east, looked the option. only has to conform to the condition Remembered C is 17, D is 26, E is big the exaggerating numeral I choose D. 356.JJ, a bird flies lake that to say the DS topic. chooses E 357. This road wrote me to think the half of the day, or 拿不准 Asks mt+sp 0? 1) ms+tp 0 2) do the mp+ts 0 which positions tell me to be supposed how Xie Zheiti? 358. Under which standard deviation and m, n, s, is p same? The A. m absolute value, the n absolute value, the s absolute value, p absolute value B. m-2, n-2, s-2, p-2 C. 2m, 2n, 2s, 2p D. root number m, root number n, root number s, root number p E. m^2, n^2, s^2, a p^2 generation of numeral goes in calculated good Chooses the B mathematics slowly to think, first read an attitude to write 359.JJ, is that said on the rug has two circulars the grease stains, the area is a lot of, has 3 meter far to the wall, must do a rug to cover them, the answer is C remembers several topics, looked like the partner memory has not declined, HOHO ~ 360. Asks n 3? 1) 0.025*10^n 25 2) 0.00025*10^2n 250 chooses D 361.A, east the B two kinds east adds the weight is 120, now the always average price is P, the A unit price is 3/2 P, the B unit price is 3/4 P, asked how many B the weight is? (Numeral possibly has does not permit) retarded? 362. Some person spend some money front, the first month flower one half, receives each month all to spend one half, asked the how many months do open headdress flower the money to be bigger than 19/20? A 3th B 4th C 5th D 6th E 7th this wrote me blindly to hoodwink, the perspiration... 363. How such many JJ? In sequence the latter number is the preceding number one half, the known tenth item is between 0.0001 and 0.00001, what scope asks the 12th item in? 0.000025-0.0000025 364. [ (1/3) ^2+ (1/3) (1/4) ] [ (1/3) ^2- (1/3) (1/4) ] 365. Eats meal with B, selects the same vegetable, similar price. After finished up, A paid the initial cost 15% to take the tip, after B paid has folded the price 15% to take the tip, A paid 0.63 US dollar compared to B, asked the vegetable initial cost. Reference answer: 42 US dollars 366. The bird passed over gently and swiftly 湖面, the speed 18 meters/seconds, asked whether 湖面 does extend in 21 kilometers. (1) the bird flew to 20 minutes 2) the bird did not fly not to 0.4 hours reference answer: E In 367.JJ that fire ladder chart looked like the picture mistakenly, the answer 7 + roots numbers 35 should not be wrong. But the examination question a little circles, says is fire ladder elevated 60 degree against the wall and extended to 70 feet. probably this view, wording meaning explanation in vain this ladder has not been in any case depends on 60 or to depend on wall 60. But thought the fire ladder depended on wall 60 to depend on 30 also too to exaggerate has been impossible. Moreover this ladder itself takeoffs 7ft, possibly is from the fire engine 顶上去, therefore said the drawing was wrong. 368. That topic X 950, 2) each position adds together = 16 answers: A 374. A country's? ? (Has forgotten, is in any case a noun) by this country's DEBT, eliminates by this country's total population, asks some country's? ? Is within $5 of 500 (1) some country's DEBT approximately to 1, 000, 000 for ￥ 4,300, 000, 000 (2) some country's population approximately to 1, 000, 000 is 86, 000, 000 the numeral which but I bumps into absolutely and this has been dissimilar, therefore everybody certainly must know how this topic did calculate, do not have hardly to record the answer 375.x=0.01 (1+x^4) * (1+x^2) 376.

A sequence, the nth formula is 4/n-4/ (n+1), asks the 100th value 381. if a stock is originally priced at x, then the price increase by R percent, and then the price is again increaced by y dollars, what is the actual percentage by which the stock price increased from x. Pays attention to in all answers which this topic gives all to have 100 this numerals or in the denominator or in the member 382.2 machines work, the machine A 8 hours can make 7,000 products, the machine B 2 hours can make 7,000 This day A dry time is B two times, asked A does the product number accounts for the always percentage, the answer is 33.333%

Usage of him
Rule: Pronouns take nominative case in sentences following than OR as, when we're comparing people or things.
HE is smaller than I...[am small]
The dog down the street is meaner than she... [is]
Dogs are as smart as they...[are]
You want to use me, her, and them, don't you? You could, but that wouldn't be right. The subject form of the pronoun always comes after than or as. Why? There's an understood verb in the construction. That verb is dropped by ellipsis.
The accusative case - object form won't work: me am, her is, and them are are just plain wrong!
So All choices with him can be eliminated.
Now we can decide between C and E.

All ST questions:
q1. range question: 1/31+1/32+...1/40
1/40 is less than 1/31.
minimum is 1/40*10= 1/4
maximum is 1/31*10 =1/3

0-----1/8-------1/4-----1/3-----2/3----1/2---------1

1 > s > 1/4.
2/3>s>1/8
s>1/2 not possible

q3. Ask Dina. I Think Answer is D.
But Raids checks for numbers also
20^n > 1000; n is always > 0 but it cannot be said that it is a integer.

q4.concept question.
x>y?
x^2y^2=36
xy = +-6

q5.DS.simple.
c*ab >5.Is c a positive number?

q6.PS.

I was getting 0.75 +0.012 * 1000
Raid ignored 0.9 cents.?

q7.DS ratio question
R:B:G width ratio 3;2:1
width of 2 R and 3 B =5
2*4x+3*2x = 5

q8.PS.

counting principle
first position of a 3 digit number only 1to8
tens and units place dont have 5 at the same time
Total combinations= 8*10*10
combinations with 5's in tens and units= 8*1*1
so ans - 800 -8=792

q9.PS. Distance.
Initially I had this wrong

A------------------------------B ---------------------C
total average from A to B = 70 m/hr
A to B distance = 70 m
A to B speed = 40 m/hr
A to B time = t1 == B to C time
so total time = 2t
What is speed from B to C
AC=AB+BC
70*2t = 40*t + x
100t=x; ===> x/t= 100 i.e diatance from B to C

q10.PS.

got it now.
3rd digit is 1 : Fixed
1st digit: any numbers 2-9 can be placed: Total ways=8
2nd digit:total ways to arrange=7; because 3rd digit and 1st digit have consumed one each
4th digit=6 ways
total ways to do this- 8*7*6= 8p3

1) I only remember one,
in order to resolve the U.S. medical costs are too high, whatever the approach taken, inside but failed. has hospital chain and so on, the author pointed out the defeat the reason and proposes the solution

2) about deer tick Lyme disease is caused by a bacterium transmitted to humans by deer ticks. Generally deer ticks pick up the bacterium while in the larval stage from feeding on infected white-footed mice. However, certain other species on which the larvae feed do not harbor the bacterium. Therefore, if the population of these other species were increased, The number of ticks acquiring the bacterium and hence the number of people contracting Lyme disease would likely decline. There were hospital chain like. The author points out the causes of failure and to propose a solution

27) with 24) GWD-28-Q1927) with 24) GWD-28-Q19 Plankton generally thrive in areas of the ocean with sufficient concentrations of certain nitrogen compounds near the surface where plankton live. Nevertheless, some areas, though rich in these nitrogen compounds, have few plankton. These areas have particularly low concentrations of iron, and oceanographers hypothesize that this shortage of iron prevents plankton from thriving. However, an experimental release of iron compounds into one such area failed to produce a thriving plankton population, even though local iron concentrations increased immediately.Plankton generally thrive in areas of the ocean with sufficient concentrations of certain nitrogen compounds near the surface where plankton live.

Election weakened. I chose the new train to be allowed to reduce midway maintainance the time

29) a BF topic: One kind of any clever heavenly body hits to Jupiter atmosphere time definitely turned very many fragments to go in its atmosphere, because outside the J atmosphere did not include the sulfur but the atmosphere content massive sulfur (BF1), after but hit the matter which outside the atmospheric strike aroused to include the massive sulfur (BF2), therefore definitely was the fragment goes in has splashed the inside atmosphere sulfur. I have chosen the new trains can shorten the time halfway maintainance "br everywhere" br melodies

29): A BF what the hell of a time certain celestial bodies crashed into Jupiter's atmosphere into a lot of debris into its atmosphere.

18. The area of a triangle is 16*root3. What is the perimeter of the triangle?
1). It is an isosceles triangle
2). Two of the inside angles are 30 degrees.
ANS: (B)
Stmt 1) Given area = 16sqrt(3) and triangle is isosceles. Let b=base and h=height. From given 1/2*b*h=16*sqrt(3). We have 2 variables 1 equation. INSUFF

Stmt 2) Given area = 16sqrt(3) and two inside angles are 30. This implies this triangle is also isosceles, and there is extra information available (angles = 30,30,120). Let b be the base, h be the height and s be the measure of two equal sides. We have following relations
Perimeter = b+2*s, Area = 1/2*b*h, h*tan(30)=b/2, s*cos(30)=b/2 (4 equations and 4 variables). Solvable. SUFF

19. As the figure shows, A is the center of the circle, AB=AC=2, angle BAC is 120 degrees. What is the area of the triangle?
ANS: sqrt(3)
Draw a perpendicular AD to BC, AD bisects BC. Angle B = Angle C = 30.
Height = ABsin 30=1, base = ABcos30+AC cos30 = 2ABcos30=2¡î3.
Area = 1/2*base*height = 1/2*2*sqrt(3) = sqrt(3)

20. The median of the rent of the apartments is 550. What's the average (arithmatic mean) of the rent?
1). The average rent of apartments with rent higher than the median is 890.
2). There are 370 apartments with the rent higher than the median.
ANS: E
Median is basically the middle value when the rents (or items) are arranged in increasing (or decreasing) order. Average rent is (total sum of rents)/(total number of apartments). The question just gives us the median value.
Stmt 1) Average rent of apartments with rent higher than the median is 890 -> Gives gives us an average of upper half. We still have no information about the total number and total sum of apartments. INSUFF
Stmt 2) There are 370 apartments with the rent higher than the median -> Gives just the number of apartments greater than the median. No information about rents. INSUFF
Combining 1 and 2. We can find the total sum of the upper half = 890*370. Still no clue about the sum of rents of houses below the median (lower half) => INSUFF

22. Two cubes each is numbered with 1 to 6 (called dice). Tossing the dices, what is the probability that the sum of the numbers on the top is greater than 9?
ANS: 1/6
Total possibilities = 36
Favorable outcomes = (4,6), (6,4), (5,6), (6,5), (5,5), (6,6) = 6
Probability = 6/36 = 1/6

23. The first term of a geometric sequence is 1/2, and the common ratio is 1/2. The 10th term will fall into which of the following range?
ANS: (C) 0.001 ~ 0.0001
0.1~0.01, 0.01~0.001, 0.001~0.0001,0.0001~0.00001
1st term is 1/2 so 10th term would be (1/2)10 = 1/1024.
(1/1000)>(1/1024)>(1/10000) [just increasing the denominators, fraction decreases] => 0.001>(1/2)10>0.0001. (C)

24. The sides of a triangle is a, b, and c. Is it a right triangle?
1). a^2+b^2=3^2+4^2
2). a^2+c^2=3^2+5^2
ANS: (E)
*Note : a,b and c are NOT given to be integers
Stmt 1) a^2+b^2=3^2+4^2=25 -> Nothing is given about c and its relation with a and b. INSUFF
Stmt 2) a^2+c^2=3^2+5^2=34 -> Nothing is given about b and its relation with a and c. INSUFF
Combining (1) and (2), we have 3 variables (a,b,c) and just 2 equations. There are multiple values possible for a, b and c which satisfy these equations. INSUFF

25. -1

26. A list of consecutive natural numbers contains 9 and 15. Does the list contain number which can be divisible by 8?
1). The list has 10 numbers.
2). 18 is in the list.
ANS: (D)
Stmt 1) The list has 10 numbers -> the list will contain either 8 or 16 (at the minimum). SUFF
Stmt 2) 18 is in the list -> the list contains 16. SUFF
(D)

Stmt 2) if 2^a=3^b then 2^(a/b)=3. Now we know that 2^1=2 and 2^2=4. so the value of (a/b) should lie between 1 and 2 so that 2^(a/b)=3.

Hence there is atleast one more (non-integer) value of a and b (apart from a=b=0) which would satisfy the given equation. Hence statement 2 is not sufficient in itself (gives multiple values of a and b). INSUFF.
Combining (1) and (2), the only possible value for a and b is 0 (Also there are 2 equations and 2 variables). Substitute 2^a=3^b in stmt 1, we get 9^b = 2^b. This is only possible for b=0 (=> a=0). Hence a=b=0 => Parallel. SUFF

(C)

27. In the xy-plane, line A has slope a and line B has slope b. Are the two lines parallel to each other?
1). 4^a=2^b
2). 2^a=3^b
ANS: (C)
For the 2 lines to be parallel a=b. So basically the question is asking if a=b?
Stmt 1) 4^a = 2^b => 2^2a = 2^b => 2a=b. Cant be sure, because if a=b=0, lines are parallel and for non-zero values of a and b they are not parallel. INSUFF
Stmt 2) if 2^a=3^b then 2^(a/b)=3. Now we know that 2^1=2 and 2^2=4. so the value of (a/b) should lie between 1 and 2 so that 2^(a/b)=3.
Hence there is atleast one more (non-integer) value of a and b (apart from a=b=0) which would satisfy the given equation. Hence statement 2 is not sufficient in itself (gives multiple values of a and b). INSUFF.
Combining (1) and (2), the only possible value for a and b is 0 (Also there are 2 equations and 2 variables). Substitute 2^a=3^b in stmt 1, we get 9^b = 2^b. This is only possible for b=0 (=> a=0). Hence a=b=0 => Parallel. SUFF

(C)

28. If x and y are nonzero, is (x^3)(y^5)/(x^2)(y^3)>0
1). x>0
2). y>0
ANS: (A)
The question is basically asking is xy^2>0?
Stmt 1) x>0 => xy^2 is definitely greater than 0 sine y^2 is always greater than 0. SUFF
Stmt 2) y>0 => Doesn’t tell us anything about sign of x. INSUFF
(A)

29. Each segment from A to G has equal distance. Which of the following point represents [-(3^12)] ?
ANS: Point D
Distance between all points is same. Given F as 3^11 and G as 3^12. So distance between 2 points = 3^12 – 3^11 = 3^11*(3-1) = 2*3^11.
So point E = F – 2*3^11 = 3^11 – 2*3^11 = -3^11. Point D = Point E – 2*3^11 = -3^11 – 2*3^11 = -3*3^11 = -1*3^12 = -3^12

31. A ship started off at the rate of a. t hours later, in the same direction, another ship started off at the rate of b. In how many hours the second ship will catch up with the first ship?
ANS: a*t/(b-a)
Method 1: Speed Time Distance
Lets assume that after t1 hrs, 2nd ship catches the first.
Since the 2nd ship catches up, the total distance traveled by second is equal to total distance traveled by the first.
Hence b*t1 = a*t + a*t1 => t1 = a*t/(b-a)
Method 2: Relative speed
Initial distance between them = a*t.
Relative speed of 2nd ship w.r.t 1st ship = b-a.
Time taken to cover the distance = initial distance / relative speed = a*t/(b-a)
