If 64 men can do a job in 20 days, how many men will be needed to complete the work in 16 days?

$\huge \bf \underline{ \underline{Solution}}$

Let us consider the number of men as 'x'.

We'll solve this using Unitary Method.

$= \frac{64}{16} : \frac{x}{20}$

$= \frac{64}{16} = \frac{x}{20}$

$= 4 = \frac{x}{20}$

$= 80 = {x}$

$\mathtt{Final \ answer = 80 men}$
