Question

Draw a percentage bar graph for the following data:

Divisions	A	B	C	D
Total strength	65	56	54	50
students passed in English	36	42	27	23

Answer 1

Hint: We first determine the formula to find the percentage of students passed in English. We take given data as two variables and find the percentages. Then we place them in a percentage bar graph to find out the illustration.

Complete step by step answer:
We find the percentage formula for the students who passed in English.
We are taking two variables x and y. x being the number of students passed in English in a single division and y being the total strength in that same division.
So, there are four divisions named A, B, C, D.
We find the percentage theorem as ${\displaystyle \frac{x_i}{y_i}}\times 100$ where $i=A,B,C,D$.
For division A the percentage is ${\displaystyle \frac{36}{65}}\times 100=55.38$.
For division B the percentage is ${\displaystyle \frac{42}{56}}\times 100=75$.
For division C the percentage is ${\displaystyle \frac{27}{54}}\times 100=50$.
For division D the percentage is ${\displaystyle \frac{23}{50}}\times 100=46$.
Now we make a table to illustrate this

Divisions	total strength(y)	students passed in English(x)	percentages (%)
A	65	36	55.38
B	56	42	75
C	54	27	50
D	50	23	46

We place the data to find the percentage bar

Note:
Percentage bar graph is used to find the comparison. The data of a single variable should be put under a single bar. We can also relate it with the numbers of students failing the English examination.
