Yes ,It can be possible in one item 
  Because VAT will  be levied on goods and Service tax will 
be levied on providing any kind of service.
 
 Here we can see one example,
  
   like,if there is any service station for two or four 
wheelers, Mr.A come to wash their four Wheeler at the same 
time he purchase mirror or any other accessories from that 
service station the bill will be prepare with VAT and 
Service Tax.

   To wash the car = Service Tax

   To purchase any Accessories = VAT

YES IS POSSIBLE BECAUSE ONE GOODS TWO TYPES OF TAX INCLUDED
THE GOVT.

EXAMPLE; BUY ONE NEW COMPUTER 
INCLUDED THE SERVICE TAX AND VAT
