We get a volume of 248*mL

Explanation:

By definition, we have a solution that is 40% v/v.

That is "Volume of alcohol"/"Volume of solution"xx100%=40%.

And 620*mLxx40%=248*mL.

Note that I have not assumed what the alcohol is, and what the solvent is - we have assumed also (fairly reasonably) that the volumes are additive.
