Answer 2

Answer:

Step-by-step explanation

[a+b]'s one days work= 1/24

[b+c]'s one days work=1/36

[a+b+c]'s one days work=1/18

i)A's one days work=1/18-1/36

                               =1/36

∴ A alone can complete the work in= 1÷1/36= 36 days

ii) C's one days work= 1/18 - 1/24

                                  =1/72

∴C alone can complete the work in= 1÷1/72=72 days
