An article is marked up by Rs. X and the cost price of the article is Rs. 28000. If discount of Rs. X/2 is given and he gets a profit of 12.5%, then find X/2.

Correct option is B

ATQ,

$$\begin{aligned}&(28000 + X) - \frac{X}{2} = \frac{9}{8} \times 28000 \\&X - \frac{X}{2} = 31500 - 28000 \\&X = 7000 \\&\text{Required value} = 3500\end{aligned}$$​
