The family has the remaining amount of Rs. 13200 as cash. What is the monthly income of the family? Correct Answer Rs 66,000

Given

Percentages of monthly income spent on traveling = 13%

Percentages of monthly income spent on household expenses = 27%

Percentages of monthly income spent on medical expenses = 35%

Percentages of monthly income spent on insurance = 5%

The family has the remaining amount as cash = Rs. 13200

Formula used

Total expenditure = Sum of all expenses

Calculation

Let the monthly income of the family = Rs 100

Total expenditure of family = (13 + 27 + 35 + 5)% = 80%

Savings of family = (100 - 80)% of 100 = Rs 20

Now, applying proportion

⇒ 20: 100::13200: x

⇒ x = 100 × 13200/20 = Rs 66000

∴ Monthly income of family is Rs 66,000.
