\(\begin{array}{c|c} \text{Age in years} & 13 & 14 & 15 & 16 & 17 \\ \hline \text{No. of students} & 3 & 10 & 30 & 42 & 15\end{array}\)
The frequency distribution above shows the ages of students in a secondary school. In a pie chart constructed to represent the data, the angles corresponding to the 15 years old is

27^o

30^o

54^o

108^o

Correct answer is D

Number of 15- year old pupils = 30.

Total number of students: 3 + 10 + 30 + 42 + 15 = 100.

Angle = \(\frac{30}{100} \times 360°\)

= \(108°\)
