Question 479114
6 people working 5 hours per day take 2 days to plant 500 shrubs.
Find the no. of man-hrs required to plant 500 shrubs
6 * 5 * 2 = 60 man hrs
then
{{{60/5}}} = 12 man-hrs to plant 100 shrubs
:
How many days would it take 4 people working 6 hours per day to plant 800 shrubs?
Find no. of man-hrs to plant 800 shrubs
8 * 12 = 96 man-hrs to plant 800 shrubs
:
let d = no. of days to plant 800 shrubs
4 * 6 * d = 96
24d = 96
d = {{{96/24}}}
d = 4 days to plant 800 shrubs with 4 men working 6 hrs a day
