A large watermelon weight 20 kg with 96%of its weight being water . It is allowed to stand in the sun and some of the
water evaporates so that only 95% of its weight is water . Is reduced weight will be :
Let the reduced weight be `x` kg
Clearly, the quantity of pulp remains the same in both the cases.
so,(100 - 96)% of 20 kg = (100 - 95)% of `x` kg
`hArr ` 4% of 20 g = 5% of `x` kg `hArr x = (4/5 xx 20)`kg = 16kg
