Hi all. I am new to GmatClub and this is my first post ever. I just started preparations for the exams last week and I am targeting end-April for the exams. I seem to be able to get most of the questions on DS and Maths right without using elaborate equations and now I am worried. I have never liked equations plus English is my third language.

Must I learn to use all these esoteric equations to do well in Gmat? Call me crazy but my target is 770.

if you think right away that gmat need somehing of esoteric to solve......I think is wrong.

reasoning has nothing to do with the arcane ;)

How many of the 60 cars sold last month by a certain dealer had neither power windows nor a stereo?

Given: 60={Windows}+{Stereo}-{Both}+{Neither}.
Question: {Neither}=?

(1) Of the 60 cars sold, 20 had a stereo but not power windows --> {Stereo}-{Both}=20 --> 60={Windows}+20+{Neither}. Not sufficient.

(2) Of the 60 cars sold, 30 had both power windows and a stereo --> {Both}=30. Not sufficient.

(1)+(2) We can find how many had stereo, but we still cannot get how many had neither power windows nor a stereo. Not sufficient.

Answer: E.
