Total work = LCM of 9, 45 and 90 = 90 units Unit per day of A = 90/9 = 10 Unit per day of B = 90/45 = 2 Unit per day of C = 90/90 = 1 Units of work done by A in 3 days = 10 × 3 = 30 units Units of work done by B in 8 days = 8 × 2 = 16 units Remaining work = 90 – (30 + 16) = 44 units So, C has worked for 44/1 = 44 days
