Question

A mixture require A, B and C material in the ratio of 2 : 3 : 5 by volume. But Somil wants to measure out by weight. He finds one cubic feet of A is 90 kg, of B is 120 kg and of C is 150 kg. Calculate the required ratio by weight.
1. 2 : 3 : 5
2. 6 : 12 : 25
3. 3 : 4 : 5
4. 9 : 12 : 15

Answer 1

Correct Answer - Option 2 : 6 : 12 : 25

Calculations :

Volume of given materials is directly proportional to their weight.

∴ Respective ratio by weight = 2 × 90 : 3 × 120 : 5 × 150 = 6 : 12 : 25

Units are not require and do not effect if relation given in ratio.
