We begin by recognizing that a right angle is marked in the pie chart.

Since $90^{\circ}$ is $\frac{1}{4}$ of a full $\left(360^{\circ}\right)$ rotation, then $\frac{1}{4}$ of the students chose apples as their favourite fruit. If $\frac{1}{4}$ of the students chose apples, then the remaining $1-\frac{1}{4}=\frac{3}{4}$ of the students chose bananas. If 168 students represent $\frac{3}{4}$ of all students, then $\frac{1}{4}$ of all students is $168 \div 3=56$ students. Thus, 56 students chose apples as their favourite fruit.
