Question

Monthly salary of a person is ₹15,000. The central angle of the sector representing his expenses on food and house rent on a pie chart is ${60}^{\circ }$. The amount he spends on food and house rent is:

• A. ₹5,000
• B. ₹2,500
• C. ₹6,000
• D. ₹9,000

Answer 1

The correct option is B

₹2,500

Central angle of the sector representing his expenses on food and house rent on a pie chart $={60}^{\circ }$
Part of the monthly salary he is expending of food and house rent $=\frac{{60}^{\circ }}{{360}^{\circ }}=\frac{1}{6}$
Hence, the amount he spends on food and house rent $=\frac{1}{6}\times \text{Monthly salary}$
$=\frac{1}{6}\times 15,000=\text{₹}2,500$.
