Answer 1:

The total time required for fixing bars of all diameters is: time in hours of month 1 + time in hours of month 2

539 labor hours + 375 labor hours

914 labor hours

All in tons

10mm bars

Time required for 10mm bars: (total tones of 10 mm bar/ total tons of bars fixed) * total labor hours

(14.9/56.6) * 914

240.6 labor hours

240 hours and 36 minutes for 14.9 tons

16.1 hours per ton

16 hours 6 minutes per ton of 10 mm bars.

16mm bars

Time required for 16mm bars: (total tones of 16 ...
