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



        Below is simple arithmetic solution, without using Algebra.



<pre>
The entire job is 40 men * 48 days = 1920 man-days.

40 men, working 15 days, used 40*15 = 600 man-days.


The remaining job is 1920-600 = 1320 man-days.


Now only 40-16 = 24 men work.


They will complete the remaining job in  1320/24 = 55 days.    <<<---===  <U>ANSWER</U>
