# Three persons begin to walk around a circular track. They complete their revolutions in \( \Large 15\frac{1}{6}\ secs., 16\frac{1}{4}] secs.\ and\ 18\frac{2}{3}\ secs. \) rerspectively. After what time will they be together at the starting point again?

Correct Answer: Description for Correct answer:

Required time LCM of \( \Large \frac{91}{6},\ \frac{65}{4}\ and\ \frac{56}{3} \)

\( \Large \frac{LCM\ of\ 91,\ 65,\ 56}{HCF\ of\ 6,\ 4,\ 3} = \frac{3640}{1} = 3640 secs. \)
