Answer:
300 kgs
Step-by-step explanation:
Given,
fresh grapes contain 75 percent water while dry grapes contain 15 percent water.
Fresh grapes contains 75% water then remaining 25% is pulp
dry grapes contains 15% water then remaining 85% is pulp
If the weight of dry grapes is 300 kg.,
water:pulp=15%:85%
water:pulp=3:17
let water/pulp=3x/17x
if the total weight of water and pulp is 300
3x+17x=300
x=15
water is 3x=3*15=>45 kg which i 15%
pulp is 17x=17*15=>255 kg which is 85%
please find their total weight when they were fresh.
