If it takes 6 men 4 days to dig a hole 3 metres deep, how long will it take 10 men to dig a hole 7 metres deep?
Answers
Answer:
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
Answer:
Step-by-step explanation:
if 6 men can dig 3 metres deep in 4 days the we have to find how much 1 man can dig i metre deep
so first 6 men = 3 metres
1 men = x
cross multiply an x=6/3
x= 2 metres
1 man = 2 metres in 4 days
now we have to find how many days for 1 metre
so 2 metre = 4 days
1 metre = x
cross multiply and x= 4/2
x= 2 days
So 1 man can dig 1 metre in 2 days
1 man = 2 days
10 man = 10 * 2 = 20 days
1 metre = 20 days
7 metres = 140 days
So the final Answer is 10 man = 7 metres = 140 days
