Answer:

A can do a work in one day = 1 /12 work

and B can do a work in one day= 1/15 work

and A, B and C complete work in one day =1/5 work

A's work of one day +B's work of one day - A, B and C work of one day.

1/12+1/15-1/5

LCM of 12 and 15 =60

1/5-9/60 =3/60

= 1/20 work

C can alone complete work in 20 days
