Service Tax on Xeroxing

One party give the service of printing of Xerox copies. The machine belongs to uthe Company . He is providing the paper and the service of Xeroxing and he is charging @ 48 paise per copy.Ink, catraiges,oiling & maintenance of the machine is done by that person only.

While billing the person who is giving the service of xeroxing  is charging VAT @ 5% on 75% of bill value and service tax @ 10.3% on 100% of bill value. Is this ok?

Can Service Tax & VAT be levied together? If yes then what will be the proportion of bill amount on which the service tax and VAT will be levied?

Kindly reply as it is urgent..

Thanks
