Fresh grapes contain 80 % water dry grapes contain 10 % water. If the weight of dry grapes is 250 kg. What was its total weight when it was fresh ?

Quantity of water in it = (80/100 × x)kg = 4x/5 kg

Quantity of pulp in it = (x – 4x/5)kg = x/5 kg

Quantity of water in 250 kg dry grapes

= (10/100 × 250)kg = 25kg

Quantity of pulp in it = (250 – 25)kg = 225 kg

Therefore, x/5 = 225

=> x = 1125
