Gst 18% -690

total amount -5,690



Task3:-

product name

cost

quantity

logic:

1) calculate total amount 

2) check the fallowing condition

total >5,000 then provide 10% discount of given total and display final amount

total >2,000 and <5,000 then provide 5% discount of given total and display final amount
