Given, incomes of X and Y are in the ratio of 8 : 7 and their expenditures are in the ratio 19 : 16.

Let the incomes of X and Y be 8a and 7a

Let the expenditures of X and Y be 19b and 16b

Each saves Rs. 1250

⇒ 8a – 19b = 1250 -------- (1) and 7a – 16b = 1250 ------- (2)

Equating both equation

⇒ 8a – 19b = 7a – 16b

⇒ a = 3b

Substituting value of a in eq1

⇒ 24b – 19b = 1250

⇒ b = 250

Thus, a = 750

X’s income = 8a = Rs. 6000

Y’s income = 7a = Rs. 5250
