Direction: The following pie-chart shows the marks scored by a student in different subjects - viz. Physics (Ph), Chemistry (Ch), Mathematics (M), Social Science (SS) and English (E) in an examination. Assuming that total marks obtained for the examination is 810. Answer the questions given below.
-
The marks obtained in Mathematics and Chemistry exceed the marks obtained in Physics and Social Science by
-
- 50
- 30
- 40
- 45
Correct Option: D
Sum of corresponding angles of Maths and Chemistry
= 90 + 70 = 160°
Sum of corresponding angles of Physics and Social Science
= 85 + 55 = 140°
Difference = 20°
∵ 360° ≡ 810
| ∴ 20° ≡ | × 20 = 45 | 360 |
