Question 170

Ratio of earnings of A and B is 8 : 9 respectively. If the earnings of A increased by 50% and the earnings of B decrease by 25%, the new ratio of their earnings becomes 16:9 respectively. What are ‘A’ earnings ?

Solution

Let the earnings of A and B be 8k and 9k respectively.

New earnings of A = 150/100 * 8k = 12k

New earnings of B = 3/4 * 9k = 6.75k

So, 12k : 6.75k = 16 : 9

But, from this equation, we cannot determine the value of k.

So, option d) is the correct answer.
