Question

If 20 men can build a wall in 5 days. How many more men will be required to build the same wall in two days?

Answer 1

One way to look at it is as an indirect ratio (if I recall the term correctly, it's been over 50 years) .

20 men times 9 days equals 12 men times X.

So, if 20×9=180 then 12×X=180

Dividing 180 by 12 = 15

It would take 15 days
