ATQ, Let total work = 420 days (LCM of 84, 105 and 60) Amount of work completed by Anuj in one day = 420/84 = 5 units Amount of work completed by Bittu in one day = 420/105 = 4 units Amount of work completed by Chintu in one day = 420/60 = 7 units Amount of work completed by Anuj, Bittu and Chintu together in 12 days = 12 × (5 + 4 + 7) = 192 units Amount of time taken by Anuj and Chintu together to complete the remaining work = (420 – 192)/12 = 19 days Desired time = 12 + 19 = 31 days
