A, B and C start at the same time in the same direction to run around a circular stadium. A completes a round in 252 seconds, B in 308 seconds and c in 198 seconds, all starting at the same point. After what time will they again at the starting point ?
L.C.M. of \(252, 308\) and \(198 = 2772\)
So, \(A, B\) and \(C\) will again meet at the starting point in \(2772\) seconds.
i.e. \(46\) minutes \(12\) seconds.
