Question

By selling an article for Rs.$24$, a trader loses as much percent as the cost price of the article. Write an equation to express this information and check if it is convertible to a Quadratic Equation.

Answer 1

let the cost price be $x$

$loss=x\%$

$\frac{x}{100}\times x=\frac{x^2}{100}x-\frac{x^2}{100}=24100x-x^2=2400x^2-100x+2400(x-40)(x-60)=0x=40,60$
