Fresh grapes contain 80% while dry grapes contain 10% 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: Option B
Solution (By Examveda Team)
Quantity of water in 250 kg dry grapes, $$ = \frac{{10}}{{100}} \times 250 = 25\,{\text{kg}}$$ Then, pulp of grapes = 225 kg We get 20 kg pulp in 100 kg fresh grapes. To get 225 kg pulp , we need fresh grapes,$${\text{ = }}\frac{{100 \times 225}}{{20}} = 1125\,{\text{kg}}$$This Question Belongs to Arithmetic Ability >> Percentage
Problem can be solved in single step: Ratio of pulp in dry fruit/ pulp in fresh fruit X weight of dry grapes
90/20 x 250 = 1125 kg.
fresh grapes pulp-20%
and dry-90%
20/100*x=90/100*250
x=1125
1125
