Answer 1

it is a case of inverse variation
56×42÷14=168

Answer 2

Answer:

168 men

Step-by-step explanation:

We are given that  56 men can do a piece of work in 42 days

1 man can do work in days = $56 \times 42=2352$

Let the number of men be x who completes work in 14 days

So,x men can do work in =14 days

So, Number of men required to do work in 14 days = $\frac{2352}{14}$

                                                                                     = $168$

Hence 168 men can complete work in 14 days.
