Answers
Answer:
The bar graph is one of the frequent methods used to present various types of data. It is usually asked in the data interpretation section of the competitive exams. In data interpretation, it is the representation of data where the vertical bars are placed at equal distance from each other. The value of the data represented is given by the height and length of the bars. The width here is not important it is only used so that the presentation is clear.
They are plotted against the horizontal axis known as the x-axis. The value can be shown by coloured or shaded vertical bars of equal width. In a horizontal bar graph, the values are plotted against the vertical axis called the y-axis. They are commonly used as the data can be easily analyzed.
Explanation:
We use the concept of ratio and proportion to answer the given questions.
We know that the total number of students in a class = 30.
The total number of students who like football = 6.
The total number of students who like cricket = 12.
Since the remaining students like tennis, the total number of students who like Tennis = The total number of students in a class - The total number of students who like football - The total number of students who like cricket = 30 - 6 – 12 = 12
Therefore, the total number of students who like Tennis = 12
(a) We need to find the number of students liking football to the number of students liking tennis.
The number of students liking football to a number of students liking tennis = The total number of students who like football: The total number of students who like Tennis = 6:12.
Now, in order to write the ratio in its simplest form, we divide 6 and 12 by a common factor of 6.
Therefore, the number of students liking football to the number of students liking tennis = 1:2.
(b) We need to find the number of students liking cricket to the total number of students.
The number of students liking cricket to total number of students = The total number of students who like cricket: The total number of students in a class = 12:30
Now, in order to write the ratio in its simplest form, we divide 12 and 30 by a common factor of 6
Therefore, the number of students liking cricket to the total number of students = 2:5
