A voltmeter of least count 0.1V has a positive zero error of 5 devisions .If it reads 25 devisions in a particular circuit, what is the magnitude of potential difference?

positive error of 5 divisions
so 0volt =5 division
25 division =20division actually
so actual potential difference
0.1*20=2volts

I am little confused about this zero error and it's correction.
