Answer 1

Given:-

when selling price is 480 then loss =20%

Formula used:-

If an article is sold at a profit of x% and cost of price is CP then the selling price will be;

selling price= [(100-y)/100]×CP

Calculation:-

let the cost price of the article be x according to the question, 80% of x=480

x=(480/80)×100

=600

Required profit % = 130% of 600

= Rs.780
