Question 66

Fresh grapes contain 80 per cent water while dry grapes contain 10 per cent water. If the weight of dry grapes is 250 kg what was its total weight when it was fresh ?

Solution

Solid part of fresh grapes = Solid part of dry grapes

let the weight of fresh grapes be x kgs

x * 0.2 = 250 * 0.9 [fresh grapes have 20% water, so rest solid part]

x = 1125 kgs
