100kg --> 72kg of water, 28kg (rest of the fruit)
28kg of fruit remains, while 20% of the 72kg of water remains = .2*72 = 14.4

So weight of dry fruits = 28+14.4 = 42.4 kg of dry fruit..

hm... I'll got with D as that's the closest.

I will go for A.
fresh fruit contains 72% water and 28% fruit.
dry fruit contains 20% water and 80% fruit.

100 kgs of fresh fruit contains 72kgs water and 28kgs fruit.

So dry fruit can contain maximum of 28kgs fruit.

So , .8x = 28, x = 35Kgs. The remaining water from the fresh fruit will evapourate.

I disagree. the 28kg of fruit does not have a drop of water. So you cannto take 80% of 28kg.

I understand both approaches but I think A is the answer.

14.4 kilograms is not 20% of 42,40 kilograms, and dry fruit consists of 20% water and 80% fruit.

Please correct me if I am wrong.

OA is A.

Note, 28Kg of Solid material will accoutn for 80% of the overall weight of the dried fruit (as 20% of the wiegth is water in dried fruit).
