(B) Coe Coe

Answer

Correct choice: (E)

正确答案：（E）

Solution

Use logic to solve this problem. You don't actually need to use any equations. Neither Jo nor Bo has as much money as Flo. So Flo clearly does not have the least amount of money. Rule out Flo. Both Bo and Coe have more than Moe. Rule out Bo and Coe; they clearly do not have the least amount of money. Jo has more than Moe. Rule out Jo. The only person who has not been ruled out is Moe. So $\boxed{\text{(E)}}$ is the answer.

使用逻辑解决这个问题。你实际上不需要使用任何方程。 Jo 和 Bo 都没有 Flo 多钱。所以 Flo 显然不是最少的。排除 Flo。 Bo 和 Coe 都比 Moe 多。排除 Bo 和 Coe；他们显然不是最少的。 Jo 比 Moe 多。排除 Jo。唯一没有被排除的人是 Moe。所以 \boxed{\text{(E)}} 是答案。
