## Age Questions

Summary
Understanding and solving age questions in the GRE involves accurately representing ages at different times and employing strategic variable selection to simplify equations.
• Age questions require careful consideration of how ages relate to each other at different times, necessitating a dynamic approach to variable selection.
• A common mistake is to treat ages as static numbers without accounting for their change over time, which can lead to incorrect equations.
• Choosing variables to represent current ages and using addition or subtraction to adjust for past or future ages can simplify problem-solving.
• Creating equations based on the relationships between ages at different times is crucial for solving these types of questions.
• A practical example demonstrates how to set up and solve an equation by selecting variables for current ages and adjusting for future ages to find the solution.
