Question

A TABLE marked at Rs 15000 is available for Rs 14400 . find the discount percent.

Answer 1

Marked price, MP = Rs. 15000
Selling price, SP = Rs. 14, 400
Let rate of discount = x %
discount = ​x % of 15000 = $\frac{x}{100}\times 15000=Rs.150x$

$$\begin{gathered} SP=MP-discount \\ \Rightarrow 14400=15000-150x \\ \Rightarrow 150x=15000-14400 \\ \Rightarrow 150x=600 \\ \Rightarrow x=\frac{600}{150}=4 \end{gathered}$$
Rate of discount = 4 %
