Question

6 men take 4 days to dig 3 metres , how many days will 10 men take to dig 7 metres deep

Answer 1

Answer:

Six men get 3m dug in 4 days, so their rate is 4/3 days per meter. Then 6 men would take 7*4/3 = 28/3 days to dig a hole 7m deep. But you're using 10 men, so they will take (6/10) * (28/3) days, which comes to 5.6 days

Step-by-step explanation:

Answer 2

Answer:

Let’s see. Assuming the hole is long enough (wide enough, whatever) that you can get 10 men into it without interfering with each other, and also assuming that it takes the same linear amount of time to dig the hole deeper,

Six men get 3m dug in 4 days, so their rate is 4/3 days per meter. Then 6 men would take 7*4/3 = 28/3 days to dig a hole 7m deep. But you’re using 10 men, so they will take (6/10) * (28/3) days, which comes to 5.6 days.
