Essential Math for IR

The IR section blends logic with quantitative skills. While advanced math isn't required, comfort with basic arithmetic, percentages, ratios, and interpreting statistics is key.

What to Know

  • Percentages: Converting between fractions, decimals, and percents
  • Ratios and Proportions: Comparing quantities and scaling values
  • Averages and Medians: Summarizing data accurately
  • Reading Data: Extracting precise values from tables and charts

Handy Formulae

  • Percentage Change: \( \frac{\text{New} - \text{Old}}{\text{Old}} \times 100% \)
  • Average: \( \frac{\text{Sum of Items}}{\text{Number of Items}} \)

Tips

  • Estimate when possible to save time.
  • Don't get bogged down in calculations—focus on what the question is really asking.

Examples

  • Calculating the average growth rate from a table of yearly sales.

  • Using ratios to compare market shares in a bar chart.

In a Nutshell

Basic math skills are crucial for solving IR questions efficiently and accurately.
