Four people move along the circumference of a park. They complete one round in 6 minutes, 8 minutes, 10 minutes and 14 minutes, respectively. Since they started together, after how many hours will they meet again at the starting position?
Show answer & explanation
Correct answer: A
Explanation
The correct answer is Option 1 i.e. 14.
Time to meet = LCM of their times
LCM 6, 8, 10, and 14 = 840 minutes
Required hours = 840 ÷ 60 ⇒ 14 hours
