Answer:

x varies inversely with y.

Step-by-step explanation:

We have been given that  x men can build a house in y days.

Now, if the number of men increases then the time required to build the house will decrease.

Similarly, if we decrease the number of men then the time required to build the house will increase.

So if a quantity increases then other quantity decreases and vice versa.

Therefore, [tex]x=\frac{k}{y}[/tex]

Hence, x varies inversely with y.
