Annual Development Expenditure of a state under different heads is as follows :
Agriculture $$40\%$$
Education $$35\%$$
Industry $$15\%$$
Misc. $$10\%$$
Which one of the following charts represents this information ?

For pie diagram, find the sectorial angle in
each case as follows

		Angle
Agriculture	$$40\%$$	$$=\cfrac{(360 \times 40)}{100}$$	$$=144^{\circ}$$
Education	$$35\%$$	$$=\cfrac{(360 \times 35)}{100}$$	$$=126^{\circ}$$
Industry	$$15\%$$	$$=\cfrac{(360 \times 15)}{100}$$	$$=54^{\circ}$$
Miscellaneous	$$10\%$$	$$=\cfrac{(360 \times 10)}{100}$$	$$=36^{\circ}$$

...view full instructions

How many less letters were collected on Wednesday than on Tuesday?

A
$$40$$

B
$$30$$

C
$$20$$

D
$$10$$

Solution

Given that one square box represents $$10$$ letters.
On Tuesday there are 5 boxes.
Therefore, number of letters collected on Tuesday are $$10\times5=50$$
On Wednesday there are 4 boxes.
Therefore, number of letters collected on Wednesday are $$10\times4=40$$

There are $$50-40=10$$ letters less on Wednesday than on Tuesday.
Question 6

The given pie chart shoes the marks scored by a student in five different subjects English Hindi Mathematics Science and Social Science Assuming that the total marks obtained for the examination are $$540$$ Find the subject in which the student scored $$22.2\%$$ marks

A
Hindi

B
Science

C
Social Science

D
English

Solution

Calculating the percentage of marks in different subjects we get
Hindi $$=\displaystyle \frac{70^{\circ}}{360^{\circ}}\times 100=19.4\% $$
Science $$=\displaystyle \frac{80^{\circ}}{360^{\circ}}\times 100=22.2\% $$
Social Science $$=\displaystyle \frac{65^{\circ}}{360^{\circ}}\times 100=18.1\% $$
English $$=\displaystyle \frac{55^{\circ}}{360^{\circ}}\times 100=15.28\% $$
Question 7
1 / -0

The horizontal line in a bar graph is called:

A
$$x$$-axis

B
$$y$$-axis

C
Imaginary axis

D
None of these

Solution

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 8
1 / -0

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 9
1 / -0

In statistics a suitable graph for representing the partitioning of total into sub parts is?

A
A bar graph

B
A picto graph

C
A pie graph

D
A line graph

Solution

In statistics a suitable graph for representing the partitioning of total into sub parts is a pie graph.
Question 10
1 / -0

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).
