Answer
Given,
Number of students who liked Social Studies = 40 - (15 + 12 + 8) = 40 - 35 = 5.
The data to be represented is:
| Subject | Number of students |
|---|---|
| Mathematics | 15 |
| Science | 12 |
| English | 8 |
| Social Studies | 5 |
Taking the subjects on the horizontal axis and the number of students on the vertical axis (scale: 1 unit = 1 student), the bar graph is drawn with bars of equal width and equal spacing.
