The income of Suresh and Rakesh are in the ratio 5 : 4 and their expenditure are in the ratio 3 : 2. If each saves Rs. 6000, then Suresh’s income can be: सुरेश और राकेश की आय 5: 4 के अनुपात में है और उनका खर्च 3: 2 के अनुपात में है। यदि प्रत्येक 6000 बचाता है , फिर सुरेश की आय हो सकती है:

Let Suresh's income = 5x and Rakesh's income = 4x. Let their expenditures be 3y and 2y respectively. Savings = Income - Expenditure. For Suresh: 5x - 3y = 6000. For Rakesh: 4x - 2y = 6000. Solve the system: From the second equation, 2y = 4x - 6000, so y = 2x - 3000. Substitute in first: 5x - 3(2x - 3000) = 6000, giving 5x - 6x + 9000 = 6000, so x = 3000. Suresh's income = 5x = 5 × 3000 = Rs. 15000.
