GRE Percent Problems

Published February 28, 2025 · 6 views

Percent questions often appear in word problems and data interpretation.

Key Points

  1. Percent change = (new minus old) divided by old times 100
  2. Part = percent times whole
  3. A 20 percent increase followed by a 20 percent decrease does not return to the original
  4. Convert percents to decimals
  5. Check the base amount

Expert Tip

Always identify the base carefully.
