Mathematics Question on Equations
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 ?
A
1000 kg
B
1125 kg
C
1225 kg
D
1100 kg
Answer
1125 kg
Explanation
Solution
Let's take,
Solid part of fresh grapes = Solid part of dry grapes
Assume the weight of fresh grapes be x kgs
x × 0.2 = 250 × 0.9 (as in fresh grapes there is around 20% of water and the rest is solid part)
By Solving the equation we get,
x = 1125 kgs
The correct option is (B)
