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

  • A.
    27o
  • B.
    30o
  • C.
    54o
  • D.
    108o
Correct Answer: Option D
Explanation

Number of 15- year old pupils = 30.

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

Angle = (frac{30}{100} times 360°)

= (108°)
