(a) 1000 kg
(d) 1225 kg
(b) 1100 kg
(c) 1125 kg​

Answer 1

Answer:

In dry grapes, 10 percent is water and 100−10=90 percent is pulp. In fresh grapes, 80 percent is water and 100−80=20 percent is pulp. Total weight of dry grapes is 250 kg. ⇒90100×250=225 kg.

Step-by-step explanation:

Quantity of water in 250 kg dry grapes,

=10100×250=25kg

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,

= 100×22520=1125kg
