[camitava]

Boys,
I am having a problem -

Code: Select all

The table above shows the number of vehicles at Bill’s car
dealership that have certain features. No vehicle has all three
features, but 10% have power windows and anti-lock brakes,
15% have anti-lock brakes and a CD player, and 22% have
power windows and a CD player. What percent of the
vehicles at Bill’s car dealership have a CD player but no
power windows or anti-lock brakes?
(A) 25
(B) 18
(C) 11
(D) 3
(E) 0

But don't know which one will be the answer! Can u pls help me out?

I think the table that the question references is necessary to solve this one.

My apology! I am sorry for the fact that I failed to provide you all the complete question set. However, now look at it -

power windows 60%
anti-lock brakes 25%
CD player 40%

Guys need ur help!

[ratindasgupta]

is the answer D?

[ri2007]

This is the way I would solve it

Power Window + CD player = 22
Anti Lock System + CD = 15

So Total Overlap With CD =22+15 =37

Total CD player = 40

So Total CD without oerlap =40-37 = 3

The rest of the info is not needed

Pls let me know if i am correct or have gone wrong some where.

I agree. Ans Shoud be 3

[samirpandeyit62]

RI you have solved it in a perfect GMAT style. It should be 3 only.
