|
Suppose the incomes of A and B are 3x and 5x respectively. And The expenditures of A and B are 4y and 7y respectively. |
Given: A and B save Rs. 16,000 and Rs. 26,000 respectively So, (3x – 4y) = 16000 And (5x – 7y) = 26000 |
|
Solve the equations. |
⇒ x = 8000 and y = 2000 |
|
|
Hence, Difference (in Rs.) between their expenditures = 7y – 4y = 3y = 6000 |
