Total hours of work
=Number of workers×days × hours per day
=10×6×5
=300
Total hours required
That is a total of 300 hrs required to mow 5 acres
Time for mowing one acre=300/5 =60 hrs
Time for mowing 4 acres=60×4
=240 hrs
If there are 8 men and 4 hours of work per day
Amount of time per day=8×4 =32 hrs
Days required= total time/ time per day
=240/32
=7.5 days
Therefore,
Number of days required = 7.5 days
