The following pie diagram shows the amounts that a family spends on: food, clothing, rent and miscellaneous expenditure and savings. If the monthly income of the family is 60,000, then monthly savings are: Correct Answer 6,000
Given:
Monthly income of family = Rs. 60000
Concept used:
Monthly savings = Total income × (Angle of savings in pie chart)/360°
Calculation:
Angle of savings in pie chart = 360° – (Sum of others angle)
⇒ Angle of savings = 360° – (72° + 72° + 72° + 108°)
⇒ Angle of savings = 360° – 324°
⇒ Angle of savings = 36°
Monthly savings = Total income × (Angle of savings in pie chart)/360°
⇒ Monthly savings = 60000 × 36°/360°
⇒ Monthly income = 60000 × 1/10
⇒ Monthly income = 6000
∴ The monthly savings is Rs. 6000.
