    Solution

    ATQ,

    Work Rates: Aman completes 1/20 of the work per day. Bhanu completes 1/30 of the work per day. Chinu completes 1/60 of the work per day.

    Work Schedule:

    Total Time: In 3 days, 1/5 of the work is completed. Total work = 1 unit. Cycles needed = 1/(1/5) = 5. Total time = 5×3 = 15 days.
