Answer»

Let X be any integer such that 7x and 4x be the earnings of A and B respectively.

According to the QUESTION, new earnings of A = (100 - 20)% of 7x

And new earnings of B = (100 + 25)% of 4x

The ratio of the new earnings = 5 : 3

So, (80% of 7x)/ (125% of 4x) = 5/3

Since the information is not enough to CALCULATE the expenditure of either A or B. Hence, the expenditure cannot be determined.
