Numerical Ability:
  • Numerical Computation: It involves the basic principles of arithmetic like addition, subtraction, multiplication, and division.
  • Numerical Estimation: It tests the individual’s ability of solving straightforward questions as fast as they could. It depends on how fast each individual answers.
  • Numerical Reasoning: These kinds of questions are answered based on the reasoning done on the information provided. Such reasoning is based on real time scenarios like financial data etc.
  • Critical reasoning: Information is provided that requires you to interpret it and then apply the appropriate logic to answer the questions.
  • Data Interpretation: It determines a person’s ability to extract the correct data from tables, graphs and charts.
Important topics of Numerical Ability:
