141.    There are 100 pounds of fruit and water in the fruit is 99% by weight.  After the fruit are dried and some water evaperates, water in the fruit is 98% by weight. How does the water weigh after the fruit are dried.
40 50 60,选了50 请问这道题的思路,谢谢

开始时99% WATER

说明有1单位FRUIT  99单位WATER

现在98% WATER FRUIT仍然是1

说明WATER有49

所以出去了50

我是这样理解的

还两天考试 后天13:15...

我是SB 谢谢

How does the water weigh after the fruit are dried.

关键是这是问的剩下的水还是出去的水

有个JJ说选项里没有49 所以这里应该问的是出去的水
