The pie chart represents the sports played by some Primary 6 pupils. The number of pupils who played each sport is shown in the table. How many pupils played soccer?

1. Identify the fraction of pupils who play basketball

The pie chart shows a right angle ($90^\circ$) for Basketball. This represents $\frac{90}{360} = \frac{1}{4}$ of the total number of pupils.

2. Calculate the total number of pupils

Since $\frac{1}{4}$ of the pupils is $47$ (from the table),
Total number of pupils $= 47 \times 4 = 188$.

3. Calculate the number of pupils who played soccer

Number of pupils who played soccer $= 188 - 47 - 38 - 75 = 28$.
