Part of the work done by A and B in one day = (1/40) + (1/50) = 9/200 Part of the work done by A and B in 10 days = 90/200 Remaining work = 1 – (90/200) = 110/200 Let the time taken by C alone to complete the work be ‘c’ days. So, (90/200) + (10/c) = 110/200 10/c = (110/200) – (90/200) c = 100 So, time taken by C alone to complete the work = 100 days
