Question

Ratio earnings of A and B is 4:7 . If the earnings of A increase by 50% and those of B

decrease by 25%, the new ratio of their earning becomes 8:7. What is A’s earning?

Becomes 8:7. What is A’s earning?​

Answer 1

☆Answer☆

Let the earnings of A and B be Rs.4x and 7x respectively.

After 50% increase.

A's earnings = 150% of 4x

After 25% decrease,

B's earning = 75% of 7x

Ratio = 150% of 4x : 75% of 7x = 8 : 7

But their total earnings are unknown.

Hence A's earnings can't be known.
