Answer 1

Answer:

15

Step-by-step explanation:

given, 10 workers can do a work in 6 hours.

let the no. of men required be x

it is a case of inverse variation.

so we have,

10*6=x*4

x=(10*6)/4

x=15

so 15 workers will be required to do the same work in 4 hours.

Answer 2

Answer:15

10 workers for 6 hours,

Then how many workers for 4 hours?

So 6×10÷4= 15

So answer is 15 by me
