Answer:- 4

Explanation:-

Solution:

Selling price after given 20% discount

\begin{aligned} = 150 \times \frac{(100 - 20)}{100} \\ = 120 \\ So, \\ \Rightarrow 120 \times \frac{x}{100} = 108 \\ \Rightarrow x = 90 \end{aligned}

$\eqalign{ & = 150 \times \frac{{\left( {100 - 20} \right)}}{{100}} \cr & = 120 \cr & {\text{So,}} \cr & \Rightarrow 120 \times \frac{x}{{100}} = 108 \cr & \Rightarrow x = 90 \cr}$ ∴ Required additional discount = (100 - 90)% = 10%
