Question

The incomes of a and b are in the ratio 7 : 4 and their expenditures are in the ratio 9 : 5. If each saves rs. 500, find their respective incomes.

Answer 1

Answer:

A income = 5250 and B's income = 3000

Step-by-step explanation:

let the incomes be = 7x and 4x

expenditures be = 9y and 5y

now,

7x - 9y = 500

4x - 5y = 500

( solving the equation we get )

x = 750 and y = 500

then,

A's income = 7x = 7*750 = 5250

B's income = 4x = 4*750 = 3000
