Answer 1

Answer:

1400,1000

Step-by-step explanation:

Since the ratio of A and B are in the ratio of 7:5, So we can assume their income are 7x and 5x and their expenditure as 9y and 8y.

According to the given condition,

7x - 9y = 500 [A's expenditure increased by 100}

5x - 8y = 200 [Decrease by 200]

On solving (i) * 8 & (ii) * 9, we get

56x - 72y = 4000

45x - 72y = 1800

--------------------------

11x = 2200

x = 200

Therefore:

Income of A = 1400

Income of B = 1000
