I am using Manhattan Advanced GMAT Quant
, PDF version without the publisher’s imprint.
Anyway, it is on the 8th page of the 5th Chapter. I’ve read the whole chapter, but this is only an example of a GMAT-like trap, rather out of context.
I’ve done all the Manhattan Math Guides and I am used to and comfortable with the fact that Manhattan Guys make errors very, very, VERY occasionally. Therefore I wanted to confront this example with your opinion.
I am not GMAT expert, but I would like to agree with jumsumtak
, that “a negative profit” should be called “a loss”. I uphold my mind that “a negative profit” is oxymoron, thus illegal.
If I answered your question with this post, use the motivating power of kudos!
