Summary
Understanding and solving age-related questions in the GRE involves accurately defining variables to represent current ages and manipulating these variables to account for age differences at various times.
  • Age questions require a clear definition of variables to represent ages at the current time, avoiding the common mistake of treating ages as fixed numbers.
  • The strategy involves picking variables for the present age and using addition or subtraction to express ages at different times, facilitating the creation of accurate equations.
  • Equations are then formed based on the relationships between ages at different times, requiring careful consideration of how ages change over time.
  • A practical example demonstrates solving an age problem by defining variables for current ages and adjusting for future ages to form and solve equations.
  • The key to solving age problems lies in the precise definition of variables and the strategic manipulation of these variables to reflect age changes over time.
