Question

4 men or 6 boys can dig a well in 14 days. How long would 2 men and 4 boys take to dig the same well?
​

Answer 1

It will take 12 days.

Given data :

4 men or 6 boys complete in = 14 days

So,

4 men = 6 boys

4/2 men = 6/2 boys

2 men = 3 boys

So,

2 men + 4 boys

= 3 boys + 4 boys

= 7 boys

Now,

6 boys complete in = 14 days

1 boy completes in = 14×6 days

7 boys complete in = 14×6/7 = 12 days (answer)
