Correct Answer: 5


Solution : Marked Price (MP) = Rs. 1600
First discount = 10%
Final selling price (SP) = Rs. 1368
Selling price after discount = Marked Price × (1 – Discount %)
⇒ Selling Price after first discount = Rs. 1600 × (1 – $\frac{10}{100}$) = Rs. 1440
The second discount is given as $ x$%
⇒ $1440 × (1 - \frac{x}{100}) =1368$
⇒ $1440\times(\frac{100-x}{100})=1368$
⇒ $100-x=\frac{1368\times10}{144}$
⇒ $100-x=95$
⇒ $x=5$%
Hence, the correct answer is 5.
