Question

The monthly income of A and B are in the ratio 3:4 and their monthly expenditures
are in the ratio 5:7. If each saves ₹5,000 per month, find the monthly income of each.​

Answer 1

Answer:

Monthly income of A:B = Rs.30,000 : Rs.40,000

Step-by-step explanation:

x be income

3x : 4x

y be the expenditure

5y : 7y

A         3x - 5y = 5000

B          4x - 7y = 5000

solving the equations,

         x=10,000

         y=5,000

income A:B = 3x : 4x

                    = 30,000 : 40,000
