Let the unknown value be 'x'.
20 men = 10 days
x men = 6 days
This is an inverse variation because, when the number of man increases, the number of days needed to complete the work decreases (and vise versa).
So, we should do straight multiplication.
20*10 = 6x
20*10/6 = x
200/6 = x
33.34 = x
It would take at least 34 men to complete the job in 6 days.
Hope this helps you!

In 10days a man can finish a job
in 1 day a man can do 1/10 of job
in 6days a woman can finish a job
in 1days a woman can finish a job
