Question
The ratio of the volumes of containers A, B, and C is
5:3:2 respectively. Volume of container D is 7 liters less than that of container A. If the difference between the volumes of container A and container C is 30 liters, what is the ratio of volume of container B to container D?Solution
Let volumes be 5x, 3x, and 2x respectively.
Volume of D = 5x - 7
ATQ,
5x - 2x = 30
Or, 3x = 30
Or, x = 10
B = 3 × 10 = 30
D = 5 × 10 - 7 = 43
Required ratio = 30:43
