and levying 10% VAT it is sold at Rs 4,400, find the discount percent.​

Answer 1

mp=4500

let discount %be x

sp=mp-discount %of mp=4500-x/100×4500=4500-45x

Explanation:

sp with 10%vat=sp+vat%of sp

4400=4500-45x+10/100(4500-45x)

4400-4500=(-450x+(4500-45x)/10

-1000=(-450x+(4500-45x)

-1000-4500=-495x

495x=5500

x=5500/495=11.11%
