Hi All,

In case of DS question if D is the answer isn't it necessary for the computation to give the same answer from both the given statements.

I understand that many a times in DS questions its not at all necessary to do the computation till the end but still this can be used as a verification technique (provided u have time).

Fo example in the question below though the answer is D the computation results differently.

If today the price of an item is $3,600, what was the price of the item exactly 2 years ago?
(1) The price of the item increased by 10 per-cent per year during this 2-year period.
(2) Today the price of the item is 1.21 times its price exactly 2 years ago.

let's start with your example first....
here the answer is D, and unlike what you wrote, the computation gives the same answer for both statements. check your calculations.

in general - GMAT never claims or requires that the answer should be the same in such situations - so in principle the answers to the stem can be different and the answer to the question still be D. but - i have never seen a question that does tricks with this... if the answer is D - the answers to stem are the same.

I wouldn't rely on it for choosing an answer, but i would use it as an alarming device... (i.e. if answers are not the same, either check the calculations or check the answer)

The information in (1) will never contradict the information in (2). Thus, if each of (1) and (2) is sufficient, (1) and (2) will yield the same answer.
