Hi,
I come to you first, to double check, and then to maybe recap for someone else's use, if what I noticed is confirmed to be mistakes from one of the first books edited including integrated reasoning: Conquering GMAT Maths and Integrated Reasoning", McGraw Hill's, second edition.
Chapter 6, "Integrated Reasoning Questions", page 26. , on the True of False question: the second proposal is different from the one in the solution, and makes the reader feel confused and, of course, mistake on the answer:
- in the statement : "The total number of deliveries to Cambridge, MA, in 2009, was approximately 145,000."
- in the "solution" : "The total number of items delivered in Cambridge, MA, in 2009, was approximately 145,000."
Did I miss something ?
page 80. : question 1. "Which number is the GCD of 45 and 75 ?"
solution p.83 "B"= 225
But I would say...
45 = 3*3*5 = 3^2 * 5
75 = 3*25 = 3* 5^2
GCD(45;75) = 3*5 = 15, answer C. Right ?
Thanks for your opinion.
Regards,

When you start using study materials outside of the top recommendations, you will run into some problems with flaws in them. Classic example is the 1,012 GMAT questions book by Princeton Review: every problem set had 2 wrong answers, and sometimes the solution would solve a problem that wasn't part of the problem set.
Do yourself a favor and study from the best sources.
