Question

An electronics dealer offers a discount of $10\%$ on the marked price of electronics. He still makes a profit of $20\%$. If his gain on the sale of one electronic items is $Rs4500$, find the marked price of the article.

Answer 1

$4500=\frac{1}{5}$ of C.P

$C.P=22500$

$S.P=27000$

MP * $90/100=27000$

$MP=27000\times \frac{100}{90}$

$MP=30000$
