$\green{\underline \bold{Given :}}$

• Expense ratio of A & B is 9:8

$\large{\orange{\underline{\tt{Solution :-}}}}$

$\:\:$

Since the ratio of A and B are in the ratio of 7: 5, so we can assume:

• Their income are 7x and 5x
• Their expenditure as 9y and 8y.

According to the given condition,

7x - 9y = 500--(1) [A's expenditure increased by 100}

$\:\:$

5x - 8y = 200--(2) [B's expenditure decrease by 200]

$\:\:$

On solving (1) & (2) , we get

$\:\:$

⇛56x - 72y = 4000

$\:\:$

⇛ 45x - 72y = 1800

$\:\:$

⇛ 11x = 2200

$\:\:$

⇛ x = 200

$\:\:$

Therefore:

⇛ Income of A = 1400

⇛ Income of B = 1000
