Official Solution: David deposits money into three accounts: Account A, Account B, and Account C. Two of the deposits are equal, while the third deposit is a different amount. Is the deposit in Account B larger than the deposit in Account C? (1) The deposit in Account A is greater than the deposit in Account B.
Two cases:
• The deposits in Accounts A and C are equal, making the deposit in Account C also greater than that in Account B (NO answer).
• The deposits in Accounts B and C are equal, making the deposit in Account B the same as that in Account C (NO answer).
Since both scenarios lead to the same conclusion (the deposit in Account B is not greater than that in Account C), the statement is sufficient.
(2) The deposit in Account A is greater than the deposit in Account C.
Two cases:
• The deposits in Accounts A and B are equal, making the deposit in Account B also greater than that in Account C (YES answer).
• The deposits in Accounts B and C are equal, making the deposit in Account B the same as that in Account C (NO answer).
Not sufficient.
