Question

The ratio of incomes of A and B is 9 : 7 and the ratio of their expenditures is 4 : 3. Find the sum of their monthly incomes if each of them manages to save Rs.4000 per month.

• A. Rs.64000
• B. Rs.36000
• C. Rs.28000
• D. Rs.60000
• E. Rs.68000

Answer 1

The correct option is A Rs.64000

For A, 9x – 4y = 4000......(i)
For B, 7x – 3y = 4000......(ii)
Solving (i) and (ii), we get x = 4000 and y = 8000.
So, income of A = Rs.36000 and income of B = Rs.28000
Total income = Rs.64000
