Suppose monthly incomes of Pawan and Sunil are 4x and 3x. Suppose their monthly expenditures are 3y and 2y. |
Since Pawan and Sunil save Rs. 4000 and Rs. 6000 respectively per month; 4x – 3y = 4000 And 3x – 2y = 6000 Solving the equations: x = 10000, y = 12000 Hence, Sum of their monthly incomes = 7x = 70000 |
