The correct Answer is:
To solve the problem, we need to set up an equation based on the information given. Let's break it down step by step. ### Step 1: Define the variable Let the price of the pen be represented by \( x \). ### Step 2: Set up the equation According to the problem, five times the price of the pen is Rs. 17 more than three times its price. We can express this relationship as an equation: \[ 5x = 3x + 17 \] ### Step 3: Simplify the equation To solve for \( x \), we first need to isolate \( x \) on one side of the equation. We can do this by subtracting \( 3x \) from both sides: \[ 5x - 3x = 17 \] This simplifies to: \[ 2x = 17 \] ### Step 4: Solve for \( x \) Now, we will divide both sides of the equation by 2 to find the value of \( x \): \[ x = \frac{17}{2} \] Calculating this gives: \[ x = 8.5 \] ### Step 5: Conclusion Thus, the price of the pen is Rs. 8.5. ---
