~~~~~~~~~~~~~~~~~~~~~~~~~~~~~



        The solution and the answer in the post by @mananth are incorrect.
        I came to make the job correctly,  properly and accurately,  in a way as it  SHOULD  be done.



person  I   6 days
He does  1/6  of the job in 1 day


Person  II   2 days
He does  1/2  of the job in 1 day


Person  III   3 days
He does  1/3   of the job in 1 day


Together they will do 


            {{{1/6}}} + {{{1/2}}} + {{{1/3}}} = {{{2/12}}} + {{{6/12}}} + {{{4/12}}} = {{{12/12}}}  = 1.


Together they make the entire job in one day
So they will take 1 day to complete the job. &nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;<<<---=== <U>ANSWER</U>
