Data collected in a survey shows that 40% of the buyers are interested in buying a particular brand of toothpaste. The central angle of the sector of the pie chart representing this information is
(a) 120°
(b) 150°
(c) 144°
(d) 40°

Solution:

Given 40% of the buyers prefer buying a particular toothpaste

We know that the total angle at centre of a pie chart is 360°

40%of 360° = 40/100×360° = 144°

So, angle in required sector is 144°

✦ Try This: Data collected in a survey shows that 25% of the buyers are interested in buying a particular brand of toothpaste. The central angle of the sector of the pie chart representing this information is (a) 120°, (b) 25°, (c) 144°, (d) 72°

Given 40% of the buyers prefer buying a particular toothpaste

We know that the total angle at centre of a pie chart is 360°

Central angle = 25/100 × 360 = 90°

So, angle in required sector is 90°
