Question

Ten men working for 5 hours a day for 6 days mow and area for 5 acres if there are 8 men working 4 hours a day to mow 4 acres of land how many days will it take

Answer 1

Answer:

Step-by-step explanation:

10 men work for 5 hours  

therefore,10×5

as 5 acres work is done in 6 days

therefore work done per day is 5/6

10×5=5/6

so,8×4=4/x

by cross multiplying  

4/x × 50 =5/6 ×24

so x=10 days

Answer 2

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
