Expert Answer
Time taken by individual to complete one round,
360/48 = 7.5 day = 180 hrs.
360/60 = 6 day = 144 hrs
360/72 = 5 day = 120 hrs.
They will after a time equal to the HCF.
180 = 22 x 5x 32
144 = 24 x 32
120 = 23 x 3 x 5
HCF = 24 x 32 x 5 = 720 hrs or 720/24 = 30 day.
They'll meet again after 30 days at the same point.
