In an exam the sum of the scores of A and B is 120, that of B and C is 130 and that of C and A is 140. Then the score of C is :
-
- 65
- 75
- 70
- 60
Correct Option: B
A + B = 120
B + C = 130
C + A = 140
On adding,
2 (A + B + C) = 120 + 130 + 140 = 390
| ⇒ A + B + C = | = 195 | |
| 2 |
∴ Marks obtained by C = Marks
obtained by (A + B + C) – Marks
obtained by (A + B)
= 195 – 120 = 75
