Is it A?

S1: tell 50% (3 out of 6) sides are red.
S2: We do not know if there is third color besides Red and White. insufficient.

I like to pick A, but I'm not so sure if A is correct. I'll go with C for this one.

Below is my reasoning:

(1) We do not know what is with the other three faces. Are there hints of red (partial?) on the other three faces?

(2) Same as above.

Using (1) and (2), if 3 faces are entirely white, and 3 faces are exactly red, then 50% of the cube is red.

Ans C

Hmm. Good stuff. I also picked A.

celiaXDN did you post the question in the wrong forum

If we disregard the use of the different words "exactly" and "entirely" then I pick A.

If we should read more into the use of these words then I pick E.

1)3 sides are "exactly" red. Are some of the other sides "partly" red and does this qualify as "red?"

2)Who knows what the three sides are that aren't entirely white.

It is very confusing, isn't it?

That is why I posted it. At first, I couldn't quite grasp what it really means.

I wonder the source of this question. I doubt if we will come across this type of question on real GMAT.
