Three Children Alice, Brain & Chris have a total of $1.20 between them. Does Chris have the most money?

i) Alice has 35 cents.
ii) Chris has 40 cents.

I'm confused with the explanation given in the book.

Is B actually right as they claim?

The best option B can give you is all three have the same amount of money, i.e $0.40

Can someone help!!!

With Statement 2, either they each have different amounts of money, in which case we can be absolutely certain that Chris does *not* have the most money, or they each have the same amount of money - 40 cents each. Then the question becomes, essentially, "If Alice, Brian and Chris each have 40 cents, who has the most money?" I have no idea what that question even means. Is the answer 'none of them', or is it 'all of them'? Can we say that Chris has the most money, since no one has less than he has, or does Chris not have the most because no one has more than he has? That's not a question of mathematics; it's a question of semantics, and that's not what the GMAT is testing.

You could justify answer choice B here, and you could justify answer choice C here. I don't think it's at all a good question, and it just seems like an example of a prep company trying too hard to be 'tricky'. You'll never find a question so ambiguous on the real GMAT.

I think B gives enough information to establish the answer to this yes/no D.S. question. If It's given that he has $0.40, either 1) they all of same amount of money or 2) someone has less and someone has more money that he does. Either way, the answer is "no", Chris doesn't have the MOST amount of money.

Statement B:

Choices for the money (in cents) could be

Alice -- Brain -- Chris ------ Does chris have the most money
0 80 40 No
80 0 40 No
60 20 40 No
10 70 40 No
40 40 40 No
To make Chris have the most money, the distribution should be

39 39 40 -- Yes, but the some does not match up to 120 cents.

Hence answer B alone is sufficient.
