Question

on the circular track of lenght 1080 m . Srikant is walking at the speed of 90m/min , venkat at 72m/min and bala at 60m/min . if all of them start walking at 5:30 am in the same direction and same starting point , then at what time will they all meet each other at the starting point .

Answer 1

First find out the time taken by each runner to cover the distance of 1080 m
Srikant will take = 12 mins
Venkant will take = 15 mins
Bala will take = 18 mins
Now take the LCM of 12,15 and 18 the answer will be 360 mins
So it means 6 hours.
The time will be 11:30am.
