Let the total work = 300 units (LCM of 20, 30 and 25) Amount of work done by A alone in one day = 300/20 = 15 units Amount of work done by B alone in one day = 300/30 = 10 units Amount of work done by C alone in one day = 300/25 = 12 units Amount of work done by A, B and C together in 4 days = 4 × (15 + 10 + 12) = 148 units Amount of work done by B and C together in 5 days = 5 × (10 + 12) = 110 units Remaining work = 300 – 148 – 110 = 42 units So, the time taken by C alone to complete 42 units work = 42/12 = 3.5 days So, C worked for 3.5 + 4 + 5 = 12.5 days
