Solution(By Apex Team)

MP = 920 After first discount Marked Price (MP) become, = 920 – 15% of 920 = 782 The Selling Price (SP) = 742.90 Let second discount was x% on 782 782 – x% of 782 = 742.90 $\frac{782x}{100}$= 39.1 782x = 3910 x = 5% Second Discount = 5% Short-Cut 920 == 15%(1st discount)) == 782 == x%↓(2nd discount) ⇒ 742.90 Then, $\begin{aligned}x\%&=\frac{(782-742.90)\times100}{742.90}\\ &=\frac{39.1\times100}{742.90}\\ &=5\%\end{aligned}$
