Correct Option: A
| A’s speed = | = 200 m/minute | |
| 5 |
| B’s speed = | = 125 m/minute | |
| 8 |
| C’s speed = | = 100 m/minute | |
| 10 |
Distance covered by C in 2 minutes = 200 metre
Distance covered by B in 1 minute = 125 metre
Relative speed of A with respect to C = 100 metre
| ∴ Time = | = 2 minutes | |
| 100 |
Relative speed of A with respect ot B = 75 metre
| ∴ Time = | = | minutes | ||
| 75 | 3 |
