A pie chart shows the monthly expenditure of the Iyer family. Rent is represented by a sector of 90 degrees. If the total monthly expenditure is Rs 48,000, what is the amount spent on rent?
Rent is Rs 12,000. A sector of 90 degrees is one quarter of the full 360 degrees circle, so rent equals one quarter of the total monthly expenditure of Rs 48,000, which gives Rs 12,000.
- ARs 8,000
- BRs 12,000Correct
- CRs 16,000
- DRs 24,000
Explanation
Rent share = 90/360 = 1/4 of total expenditure. 1/4 of Rs 48,000 = Rs 12,000. Rs 24,000 would result from treating 90 degrees as half the circle, which is wrong.
