  1. Answer:

    (a+b+c) do work in 10 days

    so,( a+b+c)’s work =1÷10 and as they work together for 4 days so work done by them in 4 days = 4÷10 =2÷5

    remaining work = 1+2÷5

    (b+c) take 10 more days to complete 3÷5 work

    so, (b+c)’s 1 day work =3÷5

    now A’s 1 day work = 1÷10 – 3÷5 = 1÷25

    A does 1÷25 work in 1 day

    therefore, A can complete 1 work in 25 day
