Question

...

GMAT TIGER · Answer

Anything wrong with the question?

go for B.

amitdgr · Answer

Is it E ?

(1) tells us out of 800, 320 are neither red nor pure woolen. The remaining 480 have 150 red sweaters. But no useful info about how many of them are pure woolen.

(2) tells us that out of 150 red sweaters , 100 are not pure wool. So the remaining 50 may be of pure wool. But no surety here also.

The wording is confusing. I jumped to B at first. I would have selected B on the test

IMO B;

B:
out of 150 100 are not madeup of wool means there are 50 sweaters made up of wool

* lets assume all swe. are either of wool or not

A: isnot suff.

yezz · Answer

FROM GIVEN

EITHER RED OR WOOL = 800-320 =480

RED ONLY = 150-X , X IS RED AND WOOL

WOOL = Y-X , Y IS WOOL ONLY

THUS

(150-X)+(X)+(Y-X) = THUS Y-X = 330 ( IE: WOOL BUT NOT RED)

BUT WE CAN NOT DEDUCT X.........INSUFF

FROM 2.....OBVIOUSLY SUFF......b

Is it safe to assume that the rest of the red sweaters are woolen ?? We'll only know when we get the OA

spiridon can we have the OA now please ??

spiridon · Answer

Those of you who selected B How many of you have seen this question before?

store has 800 sweaters 150 red 2) 100/150 of the red are not made of wool there is nothing in the world which leads to the conclusion that the rest is made of wool it can be cotton, nylon or whatever, the question does not say OA is however B I believe this question is misworded

amitdgr · Answer

I can't believe this is a real GMAT question !!! They generally don't leave any ambiguity !!!

Now I really hope I DON'T SEE THIS QUESTION ON GMAT.
