Answer: C can complete the work in 5 days
work done by A in one day= 1/20
work done by B in one day= 1/15
work done by A and B together in one day= 1/6
work done by A and C together in one day= 1/4
work done by C alone in one day= work done by A and C in one day - work done by A in one day
=(1/4)-(1/20)= 1/5
work done by C alone= 5 days
