GMAT

Comprehensive study of gmat covering fundamental concepts and advanced applications.

Basic Concepts

Quantitative Reasoning Fundamentals

Understanding the Quantitative Section

The Quantitative Reasoning section on the GMAT tests your problem-solving and data analysis skills. It covers arithmetic, algebra, geometry, and basic statistics.

Key Concepts

  • Arithmetic (fractions, decimals, percentages)
  • Algebra (equations, inequalities, word problems)
  • Geometry (lines, angles, triangles, circles)
  • Data interpretation (charts, graphs, tables)

Approaching Quantitative Questions

Focus on identifying what is being asked and eliminate unnecessary information. On the GMAT, mental math and estimation often save time.

Problem Solving vs. Data Sufficiency

The GMAT uses two question types:

  • Problem Solving: Find the right answer from five choices.
  • Data Sufficiency: Decide if the provided data is enough to answer the question.

Real-World Relevance

Quantitative skills help in everyday decision-making, like budgeting or analyzing trends in business.

Examples

  • Solving for \( x \) in the equation \( 2x + 3 = 11 \).

  • Interpreting a bar graph to compare monthly sales figures.

In a Nutshell
