16 workers working 6 hours a day can build a wall of length 150 mts breadth 20 m and height 12 m in 25 days IN how many days 12 workers working 8 hours a day can build a wall of length 800m breadthy 15m and height 6m
Read Solution (Total 1)
-
- 50 days
Total 16x6x25 or 2400 man hours, can build 150x20x12 or 36000 m³ of wall.
So to build 800x15x6 or 72000 m³ wall 4800 man hours are required (*Double work, Double men)
Hence days required for 12 workers, working 8 hrs a day = 4800/(12x8) = 50 - 7 years agoHelpfull: Yes(1) No(0)
