Question

After allowing a discount of 10% on the marked price, a trader still makes a profit of gain of 17% . By what percent is the marketed frice above the cost price.​

Answer 1

$\huge\red{Answer}$

M.P. is 1.3 times of C.P.

solution -

let M.P. is X and C.P. be Y. Given that $\frac{90}{100} X=\frac{117}{100}$ Y (as there is 10% discount on MP and 17% profit on CP). hence

$90 X = 117 Y.\\ X = 117/90 Y. \\X = 1.3 Y.$

or we can say MP is 130% of CP.
