Question

The income of Ramesh and Suresh are in a ratio of 3 : 2 and their monthly expenditures are in ratios 2 : 1. If at the end of the month Ramesh saves Rs. 25,000 and Suresh Saves Rs. 20,000, what is the difference in income between them?
1. Rs. 27,000
2. Rs. 15,000
3. Rs. 33,000
4. Rs. 17,000

Answer 1

Correct Answer - Option 2 : Rs. 15,000

Given

Ramesh’s Savings = 25,000

Suresh’s Savings = 20,000

Calculation:

Expenditure of Ramesh = 2x, Expenditure of Suresh = x

Income of Ramesh = 3y, Income of Suresh = 2y

Savings = Income – Expenditure

⇒ 3y – 2x = 25,000      ....(1)

    2y – x = 20,000      ....(2)

⇒Solving by (2 x Equation 2) – Equation 1,

⇒ x  = 10,000 and y = 15,000

Income of Ramesh = 3y = 3 x 15,000

⇒ 45,000

Income of Suresh = 2y

⇒ 2 x 15,000 = 30,000

⇒ Difference of Income = 45,000 – 30,000 = 15,000

∴ Difference of Income = Rs. 15,000
