Correct Answer: Daman
Correct Answer: 40
Explanation:
The fruit content in both the fresh fruit and dry fruit is the same.
Given, fresh fruit has 68% water.so remaining 32% is fruit content. weight of fresh fruits is 100kg
Dry fruit has 20% water.so remaining 80% is fruit content.let weight if dry fruit be y kg.
Fruit % in freshfruit = Fruit% in dryfruit
Therefore, (32/100) x 100 = (80/100 ) x y
we get, y = 40 kg.

Correct Answer: 50 %
Explanation:
Let the cost price be x and selling price be y.
Loss = x ? y
When the cost price doubles, the loss gets tripled.
So it becomes like this, 2x ? y = 3(x-y)
=> x = 2y
Loss % = (loss/ C.P) x 100 = [(2y-y)/2y] x 100= 50 %
