Given:
The monthly incomes is Rs. 64,800
the monthly expenditure incurred by a family on various items, and their savings is 360°
Formula used:
saving income = (saving angle (θ)/360°) × monthly income
Calculation:
According to the pie-chart,
⇒ Saving angle = 35°
For one month,
⇒ Saving income = (saving angle (θ)/360°) × monthly income
⇒ Saving income = (35°/360°) × 64800
⇒ Saving income = Rs.6300
⇒ Saving income in a whole year = Rs.6300 × 12 months
⇒ Rs.75600
∴ Yearly savings are Rs.75600.
Mistake Points Monthly income/saving is given and yearly saving is asked hence Saving will be more than Expenditure
