i go for (1) b (2) d As for (1) here the sales of drug manufacturers are discussed, whereas according to the question stem, we must be interested in what the hospitals sell.. hence i think B would be a better answer.

IMO C "of getting" seems to be the correct grammatical construction. Between C and E, E seems incorrect because his, her (singular pronouns) incorrectly refer to Adult Survivors(plural subject). Hence C.

IMO B Choices C, D, E sound just too awkward. Between A and B, B seems more correct to me.

freakomalay, Square is a subset of rectangle! A rectangle with all sides equal is a square.

IMO A (1) |x| > 3 x > 3 or -x > 3. In any case |x| > 1 Hence SUFF (2) |x + 8| > 3|x - 2| x + 8 > 3x - 6 therefore x 1 cannot be determined -x -8 > -3x + 6 therefore x > 7 Since a definite answer cannot be found from (2), IMO A. Plz correct if i am making any mistake.

IMO A (1) Area of triangle PQS and area of triangle QRS is given to be the same. Now both the triangles share the same base QS. Since area of a triangle is (base * height) / 2, that means the heights of both these triangles must be the same. Hence the diagonal PR is bisected by the other diagonal (common base) QS. The fundamental property of a parallelogram is : Diagonals of a parallelogram bisect each other. Hence SUFF. (2) Does not give us any assistance, regarding the other sides, or the involved angles. Hence INSUFF. OA ?

though D seems right, i think there is no problem with A either. they unambiguously refers to festivals plz explain

IMO C (1) In 1970, population in country Y = 2/3 (X).. cannot find the % decrease from 1970 - 1980 Hence INSUFF (2) In 1980, population in country Y = 1/2 (X).. cannot find the % decrease from 1970 - 1980 Hence INSUFF Considering both together, we can find the % decrease to be of 25%. Hence SUFFICIENT. 2 /3 - 1 /2 100 - ? Cross multiply.. OA ?

the link provided does not seem to work. please post the correct, working link else provide an explanation here!

Option A seems wordy to me. Also the do at the end does not seem correct. If it were not there, then probably A would have been right. IMO D.

i have probably followed a different approach.. here is my explanation.. (1) let club x have 100 members. therefore club y has 20 more members.. since you do not know the no. of members in club y INSUFF (2) let club y have 100 members. therefore club x has 30 more members.. again from the same reasoning INSUFF combine both.. let club x and club y have 100 members each.. therefore the clubs have 130 and 120 members respectively.. this condition is sufficient to answer the question.. hence SUFF. hope it was helpful.

hey, why cannot B be a correct answer ? which she in option C seems redundant to me.. in option B them refers to illustrations, and the sentence seems correct gramatically. Can anybody explain why C would be chosen over B ?

IMO E (1) 270 students attended for 2 or more days.. INSUFF (2) since we do not know the number of students who attended on a single day, we cannot calculate 10% of it.. INSUFF Combined : from 1, 630 either did not attend, or attended for a single day. however still we don't know how many attended on a single day.. hence INSUFF. Hence E. OA ??

IMO D (1) aba = a Dividing both the sides by a, we get ab = 1 Hence SUFF. (2) bab = b - SUFF by the same reasoning. Plz. explain.

IMO B (1) y here the condition |x - y| > |x| - |y| is satisfied in all cases except when x and y are both positive. In that case the condition becomes |x - y| >= |x| - |y| Hence INSUFF (2) x.y Hence the condition holds true for +x,-y and -x,+y Hence SUFF. I took x = +/- 5 and y = +/- 2 OA ?
