Question

A dealer offers a discount of 20% and still makes a profit of 20% and he further allows 4 articles free on the sale of 12 articles. Find the ratio of cost price to marked price.

Answer 1

Let the Cost price be $C$

And Let the marked price be $M$

According to question $M\times$ $\frac{4}{5}$ $\times \frac{12}{16}$ $=$ $\frac{6}{5}C$

Solving we Get $\frac{C}{M}$ $=$ $\frac{1}{2}$
