In 2025 sixty students were asked how they travelled to college. Pie chart A below shows the results of this survey. Pie chart B shows the results of a similar survey conducted 5 years earlier in 2019.

Step 1: Analyze Pie Chart A (2025).
The total number of students surveyed in 2025 is 60. The percentages for each mode of transport are:

• Walk: $10\%$
• Cycle: $25\%$
• Car: $30\%$
• Bus/Taxi: $45\%$

Calculate the sum of these percentages:

$$10\% + 25\% + 30\% + 45\% = 110\%$$

The sum of percentages in Pie Chart A is $110\%$, which indicates an inconsistency as percentages in a pie chart should sum to $100\%$.

Calculate the number of students for each mode based on these
