Age in years 7 8 9 10 11
No of pupils 4 13 30 44 9

The table above shows the number of pupils in a class with respect to their ages. If a pie chart is constructed to represent the age, the angle corresponding to 8 years old is

A.

48.6°

B.

56.3°

C.

46.8°

D.

13°

Correct answer is C

Total number of pupils : 4 + 13 + 30 + 44 + 9 = 100

The number of 8 - year olds = 13

The angle represented by the 8-year olds on the pie chart = \(\frac{13}{100} \times 360°\)

= 46.8°
