Question 1082143
28 peons x 60 days=1680 peons in 1 day
28 x 15/1680=1/4 of the work done after 15 days
(46-16) x 23/1680 +420/1680=1110/1680ths of the work done
1680-1110=570/1680 of the work left
570/1680 / 33/1680=570/33=17.27 days of work left after the 45th day
45+17.27-60=2.272727 days delayed finishing the job. ☺☺☺☺
