How many chocolate ice creams were sold?
Student Solutions
$90$ chocolate ice creams were sold.
The angle occupied by the 'chocolate' sector is $1/2(360^{\circ} - 90^{\circ}) = 135^{\circ}$.
This is $1.5$ times bigger than the 'strawberry' sector, so the number of chocolate ice creams sold is $1.5 \times 60 = 90$.
