Question

3 workers build a wall in 12 hours.How long would it have taken for 6 equally productive workers?

Answer 1

Answer:

6 hours

Step-by-step explanation:

we know,

work=men*days*hours

Given,

3 workers build a wall in 12 hours

1 work=3*12      ----(1)

How long would it have taken for 6 equally productive workers?

let x be hours and 6 men worked

1 work=6*x      ----(2)

Eq (1) equals to (2)

3*12=6*x

x=6 hrs
