# Difference between min/max clearance and min/max tolerance and relation between them

Recently I have seen a question as follows:

Dimension of the hole is $$50 +.02/-.00$$ mm and shaft is $$50 +.02/-.00$$ mm.The minimum clearance is?

My answer is .00 but the correct answer as per the website is -.02

Where am I going wrong?

The minimum clearance occurs when the largest possible shaft meets the smallest possible hole. That would be in this case a shaft of $$50.02 mm$$ in a hole of $$50.00 mm$$. The difference between the two is the $$-0.02 mm$$ from the solution you found.
