The time each man takes to complete a round of circular field,
360/48 = 7.5 days
360/60 = 6 days
360/72 = 5 days
They'll meet at the time equal to the LCM, which is 30 days

Answer: They will meet after 60 days.
Step-by-step explanation:
Since, the total distance they must cover = The circumference of the field
= 360 km,
The time taken, by cyclist first who covers 60 km per day = 360/60 = 6 days,
By cyclist second who covers 72 km per day = 360/72 = 5 days,
By cyclist third who covers 90 km per day = 360/90 = 4 days,
Thus, the time after which they will meet again = L.C.M ( 6,5,4 )
= 60
Hence, after 60 days they will meet again.
