Ques:- 100 kgs of potato contains 99% water.Its kept in the sun.The water evaporates and now amount of water is 98 %.Whats the weight of the potatoes?
Recent Answer : Added by Admin On 2022-09-28 17:44:19:
Initially, potatoes have 99% water by weight ; which means they have 1% solid non-water content.
1% of 100 kg = 1 kg
Now even when they dehydrate,this 1kg solid mass remains constant.
It is given that finally, 98% is water by weight , which implies that 2% is non-water solid.
This means 2% of total weight = 1 kg
Total weight *2/100 = 1 kg
Therefore, total weight finally = 50 kg.
