Pie chart displays entire 100%.
i.e. 18% + 40% + 21% + X = 100%
X = 100-79 = 21%
This means, 21% of the students from Primary V attended the poetry recital.
Let the total number of students who attended the poetry recital be Z.
Given that, 105 students attended from Primary V.
Using the percentage formula,
(105/Z)*100=21%
Z= (105/21)*100 = 5*100 = 500
The total number of students who attended the poetry recital are 500.
