The following pie-chart shows the monthly expenses and savings of a family. If the expenditure on the house rent is ₹ 18,000 per month, then the sum of the expenditure on food and transport is :

The correct answer is (D) ₹ 45,600.

Pie-chart data interpretation:

• In the family budget pie-chart ($360^$$\circ$ total):
• House Rent sector = $75^$$\circ$, representing ₹18,000 per month.
• Value per degree ($1^$$\circ$) = $\frac{\text{₹}18,000}{{75}^{\circ }}=\text{₹}240$$\frac{₹18,000}{75^\circ}$ = ₹240.
• Food expenditure sector = $120^$$\circ$ and Transport expenditure sector = $70^$$\circ$.
• Combined angle for Food and Transport = $120^$$\circ$ + 70^$\circ$ = 190^$\circ$.
• Sum of expenditure $= 190^$$\circ$ $\times$ ₹240 = <strong>₹45,600</strong>.
