Show answer & explanation

Correct answer: B

Explanation

The correct answer is Option 2 i.e. 12 : 16 : 25

Understanding

Application

The wages of three labourers A, B and C are in the ratio 10 : 12 : 15.

Suppose the wages of A, B and C are 10x, 12x and 15x respectively.

Wage is increased in the ratio 5 : 6, B's wage is increased in the ratio 3 : 4 and C's wage is increased in the ratio 3 : 5.

So,

New wages of A = 10x × 6/5 = 12x

New wages of A = 12x × 4/3 = 16x

New wages of A = 15x × 5/3 = 25x

So,

New ratio of the wages of A : B : C = 12x : 16x : 25x

= 12 : 16 : 25
