You are using proportion as I see.But this concept does not work for Wt of water.This is why:
(98/100) * x = 99
x = 99 * (100/98)
= 99 * (50/49)
The answer for the above is not = 50units.Am I missing something?Tx.
I am not sure I understand your question. This is the way I looked at the problem. The wt of fruit matter in the fruit does not change but the water content changes in the fruit thus altering the wt of fruit.
Also, I interpreted the problem as the wt of fruit is 100 units with 99 units of water and 1 unit of fruit matter. After the fruit has dryed and some of portion of the water has evaporated, the new ratio of wt of water to wt of fruit matter is 98%:2%. Since I have assumed that the wt of fruit matter does not change, the 2% of the new weight corresponds to 1 unit of fruit.
ie 2% of new wt = 1unit. So new wt = 1*100/2 =50.
Does that make sense? Let me know if I addressed your question...
