Assuming the linear relationship holds true, it would take 4.67 people to dig the ditch. Since there is no such thing as 0.67 of a person, the answer should be 5 people.

7 people = 8 days
x people = 12 days
x = 7*8 divided by 12
= 56/12
= 4.67
so approx. 5 people
112 people are needed
That my friend would take 11 people to dig the ditch. thanku pls. X Wouldn't it be 3 to 4 people? 3.5 to be exact.
5 days
if it takes 40 days for the whole lake to cover with lily's then it would take 20 days to cover half the lake with lily's. This is considered a math problem.
Using logic, if it takes 14 days for 6 men to complete the task, then it would take 3 men 28 days. Continuing it would take one man84 days (3 x 28) to complete. So, now moving backwards, it would take 2 men 42 days (half of the 84) and 4 en 21 days (half of 42)
