The selling price of an article is Rs. 1920 and the discount given is 4%. The marked price of the article is = ?

Answer: Option B

Let marked price = Rs. x
Selling price after 4% discount $$\text{ = Rs}\text{.}\frac{96x}{100}$$
$$\begin{array}{rl}& \therefore \frac{96x}{100}=1920\\ & \Rightarrow x=\frac{1920\times 100}{96}\\ & \Rightarrow x=\text{Rs. 2000}\end{array}$$
