1. A trader allows two successive discounts of 30% and 15% on selling an article. If he gets Rs. 476 for that article, find its marked price = ?

A. Rs. 700

B. Rs. 400

C. Rs. 900

D. Rs. 800

Solution:

\begin{aligned} Let, Marked price  =  Rs . x \\ ∴ x \times \frac{70}{100} \times \frac{85}{100} = 476 \\ \Rightarrow x = 476 \times \frac{100}{70} \times \frac{100}{85} \\ \Rightarrow x = Rs . 800 \end{aligned}
