Question

1. Monthly expenditure of a family is 60% of the monthly income. If the family saves 6,000 per month, the monthly income of the family (in rupees) is

Answer 1

Answer:-

Let the monthly income of the family be x.

Given:

Expenditure = 60% of income

⟹ Expenditure = 60x/100 = 3x/5

Also,

Savings = Rs. 6000

We know that,

Income - expenditure = savings

So, x - 3x/5 = 6000

⟹ (5x - 3x) = 5 * 6000

⟹ 2x = 30000

⟹ x = 30000/2

⟹ x = 15000

∴ The monthly income of the family is Rs. 15,000.
