A and B
I think there is a typo, B probally should be 143
Agree with you.
Yup, it's a typo, the answer choices are supposed to be:
I have a total of 3 OG 11
's. I got 1 as part of the bundle of books that is sent when you sign up for the MGMAT course. When i called to complain about all of the typos i found, i was advised that they can send the 'Official List' of typos. I refused and demanded a replacement - they sent one, but it was the same exact book. Called them a 3rd time and spoke to my rep there, she went through the questions that i knew had typos, and the book on her desk was not part of that particular 'print run' so she sent me that one.
Long story short - There is a print run of OG 11
that has several mistakes..
