A takes 32 sec to go around a circular track,B takes 24 sec and C takes 18 sec.If all starts from at the same time,in the same direction and from the same point,then after how much time will they be together again.
op:
a) 192 s
b)288 s
c) 32 s
d) 16 s
e) 252 s

• b) 288 sec.
  
  Time after which they all will be together again is the lcm of their respective times.
  So lcm of 32, 24 & 18 =288
