The question asks for the amount Carol has to give to Anne. The answer should thus be $2.

The question asks for the amount Carol has to give to Anne. The answer should thus be $2. I still believe answer is A (1$), though we don't have OA yet.

Let's go step by step.

We are told that: "Carol settles all the debts by giving money to both Anne and Bob" --> which means that by this one only action (giving money to both Anne and Bob) Carol settles ALL debts. How this can happen?

The balances of each:

Anne: +1(5-4)
Bob: +1 (4-3)
Carol: -2 (3-5)

So if carol wants to settle all the debts she must give 1$to Anne and 1$ to Bob. After this operation by Carol all the debts would be settled. So carol should give Anne 1$. Answer: A. _________________ Intern Joined: 02 Oct 2009 Posts: 16 Followers: 0 Kudos [?]: 40 [0], given: 5 Re: Debts [#permalink] ### Show Tags 10 Oct 2009, 19:11 Oh Yes!
