summary
the segment focuses on solving age-related questions in gmat, emphasizing the importance of accurately defining variables to represent current ages and using mathematical operations to account for changes over time.
  • age questions involve understanding relationships between ages at different times, requiring precise variable definition.
  • a common mistake is treating ages as fixed numbers without considering their change over time.
  • it's recommended to define variables representing current ages and use addition or subtraction for past or future ages.
  • creating equations based on these variables helps solve the questions, as demonstrated with examples.
  • the process involves careful equation setup and manipulation to find the correct age values.
