Q) There is a circular path around a field. Reema takes 22 minutes to complete one round while her friend Saina takes 20 minutes to complete the same . If they both start at the same time and move in the same direction , after how many minutes they will meet again at the starting
  • 1) 220
  • 2) 3.4
  • 3) 440
  • 4) 4.4


Answer : Option 1

Time taken by Reema to cover the path one time = 22 minutes
Time taken by by Saina to cover the same = 20 minutes
To find after how many minutes , means least time will be taken by them to meet again is
LCM of 20 and 22 = 220
so After 220 minutes they will meet.
