If y is an integer, then the least possible value of |23 - 5y| is

(A) 1 (B) 2 (C) 3 (D) 4 (E) 5

isn't the best answer E.. where |23-(5*5)|=|23-25|=|-2|=2
but the source from where i got this question states it to be option B confused here!

Hey, I know this question :) It's from OG12, sample question #50.

OA is actually true. They ask us the value of \(|23 - 5y|\), not the value of \(y\).

The minimal value of \(|23 - 5y|\) is 2, when \(y=5\), but answer is 2, not 5

I think they are looking for the least value for |23-5y| and not for the least value of 'y'.

Hence the answer is (B) = 2

this is a classic case of what you should NOT do in the GMAT... i also got the same, correct solution, BUT answered the wrong question. i answered the value of Y (5), not the value of |23-5y| (2). B is correct after re-reading the question. i would've gotten this wrong in the actual GMAT. so to everyone, be more careful than me. think about what the question is actually asking.
