Marks obtained by Sunita in her pre-board examination are as follows:

If pie chart is constructed for the above data, then what will be the angle of the sector representing marks obtained by Sunita inMathematics?

Correct option is A

Angle of sector = (Marks in the subject / Total marks) × 360°
In this case, for Mathematics:
Marks in Mathematics = 96
Total marks (sum of all subjects) = 72 (English) + 84 (Hindi) + 96 (Mathematics) + 80 (Science) + 68 (Social Science) = 400
Now, calculate the angle of the sector for Mathematics:
Angle of sector = (96 / 400) × 360°
Angle of sector = (0.24) × 360°
Angle of sector = 86.4°
So, the angle of the sector representing the marks obtained by Sunita in Mathematics is 86.4°.
The correct answer is (a) 86.4°.
