Ratio Proportion L1

The monthly incomes of Peter and Paul are in the ratio of 4:3. Their expenses are in the ratio of 3:2. If each saves Rs. 6,000 at the end of the month, their monthly incomes respectively are (in Rs.)

  1. 24,000 and 18,000
  2. 28,000 and 21,000
  3. 32,000 and 24,000
  4. 34,000 and 26,000

Answer

Income = 4x : 3x

Expense = 3y : 2y

Saving = Income - Expense = 6000

4x - 3y = 6000 and 3x - 2y = 6000

4x - 3y = 3x - 2y

x = y = 6000

The correct option is A.
