Question

In city A there lives 3600 persons out of which 2250 are adult, 1000 kids and 350 are aged persons then the corresponding angles in the π chart are respectively
1. 180°, 80° and 100°
2. 225°, 100° and 35°
3. 100°, 200° and 60°
4. None of the above

Answer 1

Correct Answer - Option 2 : 225°, 100° and 35°

Given:

Total number of persons = 3600

Number of adults = 2250

Number of kids = 1000

Number of aged persons = 350

Calculation:
Total angle in a pie chart = 360º

Angle for adults = (2250/3600) × 360 = 225º

Angle for kids = (1000/3600) × 360 = 100º

Angle for aged persons = (350/3600) × 360 = 35º

∴ Respective angles are 225º, 100º and 35º
