Answer 2

Data Inadequate

Solution:

Ratio of earnings of A and B is 4 : 7

Let the earnings of A be 4x

Let the earnings of B be 7x

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 not given

Hence A's earnings can't be determined
