Question

The monthly income of a and b are in the ratio 3:4 and their monthly expenditure are in the ratio 5:7. If each saves rs.5000 per month, find the monthly income of each.

Answer 1

Answer:

The income of A is 30000 and the income of y is 40000.

Step-by-step explanation:

It is given that the monthly income of A and B are in the ratio 3:4.

Let the income of A and B are 3x and 4x.

Their monthly expenditures are in the ratio 5:7.

Let Their monthly expenditures are 5y and 7y respectively.

Saving = Income - expenditure

Each saves ₹ 5,000 per month.

$3x-5y=5000$                 .... (1)

$4x-7y=5000$                 ..... (2)

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

$x=10,000$

$y=5,000$

Since the income of A and B are 3x and 4x, therefore the income of A is 30000 and the income of y is 40000.

Answer 2

Answer:

x= 10,000

y=5,000
