Question

The following pie chart represents the number of students interested in different sports. The total number of students is 1800. From the pie chart, find the number of students who like water polo.

• A. 90

Answer 1

The correct option is A 90
Given:

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 $30$%

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

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

$=5$%

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

$=\frac{5}{100}\times 1800$

$=5\times 18$

$=90$

Therefore, only 90 students are interested in w ater polo.
