Step-by-step explanation:
work done by (A+B+C) in an hour= 1/2
work Done by A in an hour = 1/6
work Done by B in an hour = 1/5
work Done by (A+B) in an hour = 1/6 + 1/5
= (5+6)/30 = 11/30
Work Done by C in an hour = (A+B+C) - (A+B) =
1/2 - 11/30
= (30-22)/30
= 8/30= 4/15
Hence C will compete the job in 15/4 h
