In a race of 200 metres, B can give a start of 10 metres to A, and C can give a start of 20 metres to B. The start that C can give to A, in the same race, is
-
- 30 metres
- 25 metres
- 29 metres
- 27 metres
Correct Option: C
According to the question,
∵ When B runs 200 m metres, A runs 190 metres
∴ When B runs 180 metres, A runs
| = | × 180 = 171 metres | |
| 200 |
When C runs 200m, B runs 180 metres.
Hence, C will give a start to A by
= 200 – 171 = 29 metres
