44。100 kilos fresh fruit,99% is water. After dried, 98% is water, if the weight of fruit didn't change, what's the total weight of the dried fruit? [50]
---------------------------------
搬到这里可能好点。
weight of fruit =100-99=1，他是不变的。
晒干后，weight of fruit =1占干果的2%，则total weight of the dried fruit=1/2%=50 |
