10
Step-by-step explanation:
Half of the students chose maths and the half is 20 .
And half of the maths students chose PE so the number of students that chose PE are 10.
PE is just a quarter of the pie chart and maths half of the pie chart making the total of maths and PE 75% out of the whole pie chart.
That only leaves us with 25% to calculate and we already know the amount of PE which is also 25% out of the whole pie chart and PE is 10 .
