        The solution in the post by @mananth is incorrect.

        As I say sometimes,  it is  TOTALLY  and  FATALLY  wrong.

        I came to bring a standard and correct solution to the problem.



<pre>
Working together, Peter and Steven take  5 1/3 = {{{16/3}}}  hours to make the job.

Hence, they make  {{{1/((16/3))}}} = {{{3/16}}}  of the job per hour.


In other words, their combined rate of work is  {{{3/16}}}.


Steven alone makes  {{{1/16}}}  of the job per hour.


Hence, Peter alone makes  {{{3/16}}} - {{{1/16}}} = {{{2/16}}} = {{{1/8}}}  of the job per hour.


It means that Peter needs 8 hour to complete the job working alone.   <<<---===  <U>ANSWER</U>
</pre>

At this point, the problem is solved completely.
