A, B, C start running at the same time and at the same point in the same direction in a circular stadium. A completes a round in 252 seconds, B in 308 seconds and C in 198 seconds. After what time will they meet again at the starting point ?

- 26 minutes 18 seconds
- 42 minutes 36 seconds
- 45 minutes
- 46 minutes 12 seconds
Correct Option: D
Required time = LCM of 252, 308 and 198 seconds
∴ LCM = 2 × 2 × 7 × 9 × 11
Required time = 2772 seconds
Required time = 46 minutes 12 seconds
