The following pie-chart shows the monthly expenditure incurred by a family on various items and their savings. Study the chart and answer the question that follows. If the monthly incomes is Rs. 64,800, then the yearly saving are: Correct Answer <font style="vertical-align: inherit;"><font style="vertical-align: inherit;">Rs. </font><font style="vertical-align: inherit;">75,600</font></font>

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
