No numbers in problem?

How many sig figs would you put if the original problem had no numbers in it to base your sig figs off of?

I doubt there would be a situation where there is no given number making it impossible to calculate the amount of sig figs, however you can use real life logic to figure out the amount of sig figs. For example if we were dealing with people then you would not be using any decimals.

In high school we were told to use 2 sig figs if there was any uncertainty.

This was pretty much answered but I'd like to add that if a constant is used (like pi) you should use at least 3-4 sig figs. So, it would be 3.142 for pi.
