TYPOs in MGMAT ADV Quant

[sudhir.18n]

I believe there are very few typos in this book:

ex: Page 106 try it # 4-9.. is this Question correct?

Page 86: answer 3.

can you please confirm this?

sudhir, can you describe what you think is wrong with these problems?

[sanjsingh09]

I agree with the above comment: Pg. 106 try it 4-9 (of the advanced quant book)

I believe there is a typo:

Statement (1) should have read a=b^2 NOT a^2 = b^2

I know that because in the explanation it says that b^2 must be positive so a is positive. If a^2 = b^2 as it says in statement (1), a could be positive or negative. Also when a is substituted into the equation, b^2 is plugged in for a not a^2, further indicating that the first statement should have read a=b^2.

Is this a typo or am I missing something?

in my version of the book, statement 1 does indeed say "a = b^2". If your version says something else, then yes there is a typo..

[sanjsingh09]

Oh okay, thank you for clearing that up.

That's interesting though, I didn't think there was more than one version of this book published, given that it was released quite recently. Coincidentally, others have found the same typo in their books... I guess we all have the "other version" of the book.

Nonetheless, thanks for the clarification!

my pleasure!

This is sloppy work on Manhattan's part. For the amount of money we all paid for these books they should do a better job on editing them.

I have found a few typos in my version as well. Including the one on 106... I don't why the Manhattan rep is the only one who's book reads a=b^2 bc mine says a^2=b^2 as well. This was not the first typo I found

I understand your frustration. This is a first edition of this book, and unfortunately there are errors. I apologize for the inconvenience.
