Three persons A ,B ,C run along a circular path with speeds of $6$ kmph, $4$ kmph, $8$ kmph respectively. If they start their race from the same point and at the same time and the length of circular path is $24$ km, then after what time will they meet again?

Ans: $12$ hour

Required time

$=\text{LCM}\left(\dfrac{24}{6-4},\dfrac{24}{8-4}\right)\\

=\text{LCM}(12,6)\\

=12$

(see similar question for detailed explanation)
