Question

The pie chart below shows the number of students attending a poetry
recital. If there were 105 primary V students, how many students
attended the poetry recital in all ?

Primary III
18%
Primary VI
40%
Primary IV
21%
Primary V
105

a) 400
b)500
c)600
d)700​

Answer 1

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.
