Given:
The ratio of monthly income of Ram and Rahim is 4 : 3 and the ratio of their monthly expenditures is 3 : 2.
Calculation:
Let the monthly income of Ram and Rahim be 4x and 3x
And their expenditures be 3y : 2y
Income - expenditure = saving
⇒ 4x - 3y = 5000 ---- (1)
⇒ 3x - 2y = 5000 ---- (2)
Now multiply equation (1) by and (2) by 3
⇒ - x = - 5000
⇒ x = 5000
⇒ Monthly income of Ram = 4x = Rs. 20000
⇒ Monthly income of Rahim = 3x = Rs. 15000
∴ Monthly income of Ram and Rahim are Rs. 20000 and Rs. 15000.
