Question

Tushar, Aman and akash start jogging around a park at the same time. Tushar finishes one round in 36 minutes, Aman finishes in 24 minutes and Akash finishes in 12 minutes. When will they meet at the starting point again?​

Answer 1

Answer:

For this, we need to find the LCM of 12, 24 and 36

LCM

LCM of 12, 24 and 36 is 72

So, they will meet at the starting point after every 72 minutes

Conversion

60 mins = 1 hr

72 mins = 60 mins + (72-60) mins

72 mins = 60 mins + 12 mins

So, it can also be written as 1hr 12 mins
