At first i thought even still now I think it is one of the easiest question in DS although I am wrong!!

Q:What is the value of y?

I.When y is multiplied with 6 the value is in between 41 and 45.
II.When y is multiplied with 3 the value is in between 19 and 23.

I marked D,but the answer is E.

I am going mad in my dreams too.Please clarify

Dont assume anything extra

How can you assume y is integer?

in (1) y could be 43/6 also
in (2) y could be 22/3

hence E

Many of the great achievements of the world were accomplished by tired and discouraged men who kept on working.

Well said Nitya!!

GMAT is all about trying to remove our unnecessary assumptions/conclusion blinds and read critically.

This is the thread that connects pretty much all sections of GMAT from MATH to Verbal to AWA.
