The pie-chart given below, shows the marks scored in an examination by a student in Hindi, English, Mathematics, Social Science and Science. If the total mark secured by the student was 540, then the marks secured by him in Hindi and Science together is how much less than the marks secured by him in Social Science and Mathematics together?

Correct Answer 48
Calculation
Total marks secured by the student = 540
⇒ 360° is equivalent to 540
⇒ 1° is equivalent to 540/360° = 1.5 marks
Marks secured in Hindi = 70° × (1.5) = 105
Marks secured in Science = 68° × (1.5) = 102
Marks secured in Social Science = 80° × (1.5) = 120
Marks secured in Mathematics = 90° × (1.5) = 135
Marks secured in Hindi and Science together = 105 + 102 = 207
Marks secured in Social Science and Mathematics together = 120 + 135 = 255
Their difference = 255 - 207 = 48
