Question

4 men can do a piece of work in 12days. How long does it take 6 men working at the same rate to do the same work ("SHOW WORKING")

Answer 1

Answer:

it will apply indirect variation

4men can do a piece of work in 12 days

6men will do it in x days

x=4×6/12

x=2 days

Answer 2

We can see that if the number of men increases, then the time decreases.

So, there is inverse proportion at work here.

So,

4men=12 days

1man=12×4 days=48days

So,

6men=48÷6days=8days

So, 6 men will complete the work in 8 days.
