10 masons can build a wall working 7 hrs a day in 12 days. in how many days can a work be completed by 14 persons, working 8 hrs a day
--------------
10 masons can build a wall working 7 hrs a day in 12 days.
7 hr * 12 days = 84 hours
10*84 = 840 man-hrs to build the wall
----
14 men * 8 hr = 112 man-hrs/day
840/112 = 7.5 days
