    Answer:

    given,

    A and B can finish a piece of work in 6 & 4 days respectively.

    that means,

    A’s one day work is 1/6,

    B’s one day work is 1/4.

    A started the work and do alone for 2 days,

    that means he complete 2/6=1/3 of total work.

    then, A and B do the work together,let it be X days to complete the remaining 2/3 work,

    therefore,X/6+X/4 = 2/3,

    =>5X/12 = 2/3,

    =>X=8/5=1(3/5)days,

    therefore,the time taken to finish remaining work is 1(3/5)days.

    Hope it helps u…
