15 kg of grapes, in which 90% of the content was water, were kept in sunlight. In presence of sunlight, the water content reduced to such an extent that now only 85% of the total weight of the grapes was water. Find the total reduced weight of the grapes.
Show answer & explanation
Correct answer: A
Explanation
The correct answer is option 1 i.e 10kg
Concept Used :
Weight of fresh grapes × Percentage of pulp in fresh grapes = Weight of dried grapes × percentage of pulp in dried grapes
Given :
Weight of fresh grapes = 15 Kg
Percentage of water in fresh grapes = 90%
So, Percentage of pulp in fresh grapes = 10%
Percentage of water in dried grapes = 85%
Percentage of pulp in dried grapes = 15%
Now, using the above formula
⇒ 15 × 10 = Weight of dried grapes × 15
⇒ Weight of dried grapes = 10.
Hence the Weight of dried grapes is 10 Kg.
