The pie chart shows the results of a survey on the favourite superhero of some pupils. One of the numbers in the table is covered by an ink blot.

Superhero	No. of pupils	Category
Wonder Woman	More than half	A
Ironman	30%	B
Thor	[ink blot]	C
Superman	10%	D

Fill in the boxes in the pie chart with A, B, C, and D to represent the given data in the table.

1. Identify the largest sector (Category A)

Wonder Woman (Category A) is 'More than half', which means $> 50\%$. The largest sector in the pie chart is clearly more than half the circle. So, the largest sector is A.

2. Determine the percentage for Thor (Category C)

The total percentage must be $100\%$. Since A is $> 50\%$, B is $30\%$, and D is $10\%$, the sum of A, B, and D is $> 90\%$. Therefore, C must be $< 10\%$.

3. Assign the remaining categories to the sectors based on their sizes

We have B ($30\%$), D ($10\%$), and C ($< 10\%$). Comparing their sizes:
$30\% > 10\% > (< 10\%)$
So, B is the largest of the remaining three, D is the next, and C is the smallest.
Matching to the pie chart:

• Medium sector (bottom right) = B
• Second smallest sector (top right) = D
• Smallest sector (top, next to vertical line) = C
