Question

6. Three persons A, B and C run on a circular track in 50 sec, 60 sec and 70 sec
respectively. If they start together from the same place, when do they meet again?​

Answer 1

Answer:

2100

Step-by-step explanation:

Circular track of person A = 50 sec

Circular track of person B = 60 sec

Circular track of person C = 70 sec

LCM OF 50, 60, 70 =

2100

2100 seconds = 2100/60

                        = 35

Therefore, they will meet together again at 2100 seconds or 35 minutes.
