Question

An article is sold at a loss of 20% . Had it been sold for ` 663 more, it would have fetched a profit of 12.5% . Find the cost price the article.

Answer 1

let the cp of  the article be Rs x.
sp of the article when it was at a loss of 20%=Rs{x-(x*20/100)}
                                                                       =Rs4x/5
ATP
 new sp=Rs(4x/5+663)
 profit=12.5%
 now,
 663=x*125/1000.
 therefore,x=5304.

the cp of the article is rs 5304.
