Vat charge basis

Hi,

If a manufacturer selling goods and paying excise duty also on the same goods,whether he have to charge VAT on sales price or sales price plus excise duty paid???

For ex, Mr.A manufactures goods , say Rs.1000 and on that he paid excise duty Rs.100, now on what VAT should be charged, on Rs.1000 or Rs,1,100???

Thanks in advance.....
