What does test anxiety really look like on the GMAT? For many test takers, it does not look like a panic attack. Instead, it shows up as brain fog, rereading, negative comparisons, mental noise....

Colleagues, hi
Going through some prep materials I've faced one simple Data Sufficiency question on weighted average with contradictory answer (at least from my perspective)
From simple sufficient / non-sufficient PoV I do realize that you can get answer with both statements separately.
However, if you try to calculate result using Statement (1) you will get non-integer value which can't be true in case of tickets. So from my PoV correct answer is B (as you can get proper integer answer from it).
So my question is: from GMAT perspective - should it be JUST sufficient and it doesn't matter will asnwer be valid or not OR also answer should be valid?

If an answer has to be an integer, then a proper GMAT question will always give an answer which is an integer.
We do have this question on the forum, in which that problem is fixed: https://gmatclub.com/forum/tickets-to-a ... 97149.html
Hope it helps.

Ok, so looks like my version from old Manhattan Prep Materials is simply wrong and was fixed in newer version (like you shared with me).
Thank you for your reply
