Answer:
Circumference of field =360 km
Cyclist 1 can cover 48 km in 1 day
∴ For covering 360 km=
48
360
=7.5 days
Cyclist 2 can cover 60 km in 1 day
∴ for covering 360 km=
60
360
=6 days
Cyclist 3 can cover 72 km in 1 day
∴ for covering 360 km=
72
360
=5 days
7.5 days = 7.5×24=180 hours
6 days = 6×24=144 hours
5 days = 5×24=120 hours
LCM of 180,144 & 120 is 720
Now =
24
720
=30 days
∴ The cyclist will meet after 30 days
