Question

If 56 workers can build a wall in 18 hours how many worker will be required to do the same work in 140 hours is the question of direct and Inverse variation

Answer 1

Answer:

Step-by-step explanation:

I think in place of 140 it may be 14

Hence I'm using 14 hours hear.

If it is 140 then do the same step sa I'm doing.

Let number of workers be x

56 workers=18 hours

x workers=14 hours

This is case of inverse proportion

56*18=14*x

x=1008/14=72

So 72 workers will be required
