Sure, let's break down the given problem step by step.
1. We are given that the cost of a pen is denoted as [tex]\( x \)[/tex].
2. According to the problem, the cost of the box is two times more than the cost of the pen. This means that if the cost of the pen is [tex]\( x \)[/tex], the cost of the box would be [tex]\( 2 \times x \)[/tex].
Therefore, the cost of the box is [tex]\( 2x \)[/tex].
So, if the cost of the pen is [tex]\( x \)[/tex] rupees, then the cost of the box is [tex]\( 2x \)[/tex] rupees.
