work done by A in 1 day = 1/5
work done by B in 1 day = 1/4
work done by C in 1 day = 1/10
work done by A, B, C together in 1 day = 1/5 + 1/4 + 1/10 = 20% + 25% + 10% = 55%
remaining work = 45%
work done by A and C together in 1 day = 1/5 + 1/10 = 20% + 10% = 30%
No. of days required to complete the work = 45%/30% = 1.5 day = 1day 12hrs
