Question

The pie chart given below represents the number of students interested in different sports. The total number of students is 1200. From the pie chart, find the number of students who like water polo.

Answer 1

Percentage of students interested in netball = $30$%

Percentage of students interested in soccer = $24$%

Percentage of students interested in tennis = $17$%

Percentage of students interested in basketball = $24$%

Percentage of students interested in water polo = $100$ – Sum of % of remaining sports

$=100-(30+24+17+24)$

$=100-\left(95\right)$

$=5\%$

Number of students interested in water polo $=\frac{\text{\% of students interested in water polo}}{\text{Total percentage}}\times 1200$

$=\frac{5}{100}\times 1200$

$=5\times 12$

$=60$

Therefore, only 60 students are interested in water polo.
