問一個非常笨的問題...

gwd 9-34
The weights of all dishes of type X are exactly the same, and the weights of all dishes of type Y are exactly the same. Is the weight
of 1 dish of type X less than the weight of 1 dish of type Y?

(1) The total weight of 3 dishes of type X and 2 dishes of type Y is less than the total weight of 2 dishes of type X and 4 dishes
of type Y
(2) The total weight of 4 dishes of type X and 3 dishes of type Y is less than the total weight of 3 dishes of type X and 4 dishes
of type Y

Ans: B

我想問為什麼A不對?

由A 可得 3X+2Y<2X+4Y
X<2Y
只能得到一個x的重量小於兩個Y的重量
由b可直接得出一個X重量小於一個Y的重量
