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.
Answer & explanation
Correct answer: option 1
Weight of grapes = 15 kg
Percentage of water in grapes = 90% of total weight
Percentage of pulp in grapes = 10% of total weight
Percentage of water in dried grapes = 85% of total weight
Percentage of pulp in dried grapes = 15% of total weight
Now ,
Weight of grapes × Percentage of pulp = Weight of dried grapes × New Percentage of pulp
15 × 10 = Weight of dried grapes × 15
Weight of dried grapes = 10 kg
