Calculating the Grandfather's Age

The wolf's riddle involves calculating the current age of the grandfather based on the information provided. Let's break it down step by step.

Step 1: Understanding the Information The wolf mentioned that if the grandfather lives half of what he has already lived plus one more year, he will be 100 years old.

Step 2: Setting Up the Equation Let's represent the current age of the grandfather as "x." According to the information provided, the equation can be set up as: \[ \frac{x}{2} + 1 + x = 100 \]

Step 3: Solving for x Solving the equation will give us the current age of the grandfather.

\[ \frac{x}{2} + 1 + x = 100 \]

\[ \frac{3x}{2} + 1 = 100 \]

\[ \frac{3x}{2} = 99 \]

\[ 3x = 198 \]

\[ x = 66 \]

Answer

The current age of the grandfather is 66 years.
