please mark me as brainiest
Total discount = (820 – 570.72) = 249.28 Rs.
First discount
∴ Second discount = (249.28 – 164) = 85.28 Rs.
Price of the article after first discount = (820 – 164) = 656 Rs.
If the second discount be x%, then x% of 656 = 85.28

by 1st discount -
1/5*820
=164$
after discount price = 820-164
=656$
let discount % be x %
x/100*656=570
x=570*100/656
x=87%. (app.)
