Quarterly sales (thousand €): Shop A 120 → 150; Shop B 200 → 210; Shop C 80 → 104 (first → second quarter). Which shop had the largest percentage increase?

Numerical Reasoning has 6 of the 50 questions, on both the standard and the Law version of the test. Bocconi stresses that advanced mathematics is not required: the task is to reason with the data given.
Calculations are simple; the real challenge is reading a chart or table correctly and separating the information that is critical to the answer from what is superfluous.

Ideas clave
- Table reading is the most common type (about 30% of bank questions).
- Charts and change over time follow — growth rates, trends and comparisons between years.
- Multi-source items combine two tables or a table and a text; the denominator is where most errors happen.
- Read the question before the data and extract only the cells you need.

Temas de Numerical Reasoning de Bocconi: cómo se evalúa cada uno
Un repaso tema por tema de la sección de Numerical Reasoning del official Online Bocconi Test outline:
01
Data Extraction Fácil
- Reading tables, bar and line charts, pie charts and histograms.
- Switching between representations.
- Selecting the relevant data and ignoring the rest.
Cómo aparece en Bocconi: A dense table followed by a question about one row or column. Most of the data is there to distract.
02
Quantitative Comparison Medio
- Percentages, ratios and the correct denominator.
- Weighted averages and combined groups.
- Absolute vs relative change over time.
Cómo aparece en Bocconi: ‘Which had the largest percentage increase?’ — the largest absolute change is often a different item.
03
Multi-Source Reasoning Difícil
- Combining two tables, or a table and a text.
- Applying constraints from one source to data in another.
- Checking each statement against all sources.
Cómo aparece en Bocconi: Statement-evaluation items: ‘which of the following is consistent with both tables?’.

Los 5 errores más comunes en Numerical Reasoning de Bocconi
Errores conceptuales y tácticos recurrentes que les cuestan puntos decisivos a los estudiantes:
01
Absolute vs relative change
The biggest increase in units is not necessarily the biggest percentage increase.
02
The reverse denominator
‘Under-30s among transport users’ and ‘transport users among under-30s’ divide by different groups.
03
Averaging averages
Combine groups with weights — total points over total people.
04
Reading the units
Check whether a table is in thousands, millions or percentages before comparing.
05
Reading everything
Most of the table is superfluous. Locate the question's rows and columns first.
