Study the given pie - charts and answer the question that follows.
The pie charts represent the percentage distribution of 300 students of class X in a school in six diferent sections A, B, C, D, E and F
The table shows the number of boy of class X in six different sections A, B, C, D, E and F.
| Section | A | B | C | D | E | F |
| No. of boys | 36 | 26 | 34 | 28 | ---- | 20 |
The difference between the central angles of the sectors corresponding to the sections A and F is:
Show answer & explanation
Correct answer: D
Explanation
The correct answer is option 4 i.e. 28.8º
Central angle by sector A = 20% × 360° = 72°
Central angle by sector F = 12% × 360° = 43.2°
The difference between the central angles of the sectors corresponding to the sections A and F = 72° - 43.2° = 28.8º
