Summary
The content focuses on alternative strategies for solving word problems on the GMAT, specifically emphasizing the technique of backsolving.
  • Backsolving involves starting with one of the numerical answers and working backwards to see if it makes sense.
  • A recommended approach is to start with answer choice C, which statistically offers a chance to eliminate three answers at once if it's incorrect.
  • An alternate strategy suggests starting with answer choice B, providing a statistical advantage in narrowing down the correct answer more quickly.
  • Practical application of backsolving is demonstrated through examples, showing how to efficiently eliminate incorrect answers and identify the correct one.
  • The technique is particularly useful when all five answer choices are numerical, allowing for a strategic approach to problem-solving.
