Question

If 8 men can do a job in 5 days, how much time would 10 men take to do the same job?
​

Answer 1

Answer:

If 8 men can do a job in 5 days then the ratio would be written as 8:5.

We can conclude that this is inverse proportion.

So let's consider 8/5 and 10/x.

Applying the property of inverse proportion

we can calculate:

8*5=10*x

40=10x

40/10=x

4=x

Hence it will take 4 days for 10 workers to do the same job.

Hope you find this useful.

Answer 2

Answer:

4 days

Step-by-step explanation:

Let the no. of day to do a job by 10 men be x.

no.of men =8 and 10 no.of days =5 and x

8×5=x×10

40/10=x

x=4

Therefore, 10 men takes 4 days to do the same job.
