The horizontal line in a bar graph is called:

A
$$x$$-axis

B
$$y$$-axis

C
Imaginary axis

D
None of these

In the Cartesian coordinate system, the horizontal reference line is called $$x$$-axis.
Therefore, the horizontal line in a bar graph is called $$x$$-axis.
Hence, option $$A$$ is correct.
Question 4

The incomplete pictograph shows the number of stamps(1 ticket = 4 stamps) collected by four pupils:
The missing tickets represents the number of stamps collected by Anjali.
Then how many tickets collected by Anjali?

A
$$5$$

B
$$7$$

C
$$6$$

D
$$8$$

Solution

From the given pictograph, the total tickets coolected by Lata, Kalyan, Vaishnavi are $$13$$.
Given that one ticket symbol represents $$4$$ stamps.
Therefore, total number of stamps collected by Lata, Kalyan, Vaishnavi are $$13\times4=52$$.
Given that, total number of stamps collected by four pupils is $$80$$.

Therefore the number of stamps collected by Anjali = Total number of stamps collected by four pupil - number of stamps collected by three pupils (excluding Anjali) $$=80-52=28$$

Hence, the number of tickets collected by Anjali are $$ \dfrac{28}4=7$$
Question 5

Answer the following question by reading the given pictograph.
Number of TV sets sold in the year 2005 is

A
$$1000$$

B
$$500$$

C
$$50$$

D
$$2000$$

Solution

From the given pictograph, $$2005$$ has one tv symbol.
Given that one symbol represents $$500$$ tv sets.
Therefore the $$2005$$ has $$1\times500=500$$ tv sets.
Question 6

The bar graph shows the number of cakes sold at a shop in four days. What is the difference in number of cakes between the highest and the lowest daily sale?

A
$$20$$

B
$$35$$

C
$$30$$

D
$$40$$

Solution

From the above bar graph, the highest number of cakes sold is $$45$$ (i.e., on Sunday).
and the lowest number of cakes sold is $$25$$ (i.e., on Monday).

Therefore, the difference between the highest and lowest number of cakes $$=45-25=20$$.

Hence, option $$A$$ is correct.
