The correct Answer is:
To find Raju's age, we can follow these steps: ### Step 1: Define the variable Let Raju's age be represented by \( x \). ### Step 2: Write the equation based on the problem statement According to the problem, Raju's father's age is 5 years more than three times Raju's age. Therefore, we can express Raju's father's age as: \[ \text{Father's age} = 3x + 5 \] ### Step 3: Set up the equation We know from the problem that Raju's father is 44 years old. So, we can set up the equation: \[ 3x + 5 = 44 \] ### Step 4: Solve for \( x \) To find \( x \), we first isolate the term with \( x \) on one side of the equation. We do this by subtracting 5 from both sides: \[ 3x + 5 - 5 = 44 - 5 \] \[ 3x = 39 \] ### Step 5: Divide to find \( x \) Now, we divide both sides by 3 to solve for \( x \): \[ x = \frac{39}{3} \] \[ x = 13 \] ### Conclusion Raju's age is \( 13 \) years. ---
