$1150$ students of a school who opted sports as a hobby.
How many students have book reading as a hobby?

0%
$390$
0%
$420$
0%
$440$
0%
$450$

Explanation

23% of total students opted sports as a hobby

Let total number of students be

$x$

$0.23x$

$=1150$

$\frac{23}{100}x=1150$

So,

$x=5000$

9% of

$x$ opted book reading as a hobby,

$0.09\times5000$

$\frac{9}{100}\times5000=450$

Hence, Option D is correct answer.

Study the following information carefully and answer the questions given below. A Survey of film watching habits of people living in five cities P. Q R, S and T is summarised below in a table. The column 1 in the table gives percentage of film-watchers in each city who see only one film in a week.
The column II gives the total number of film-watchers who see two or more films per week.
A city with the minimum number of film-watchers is

0%
P
0%
Q
0%
S
0%
T

Explanation

Number of film-watcher in city

$\displaystyle\, \frac{24000}{40} \times 100$ =60000

$\displaystyle\, \frac{30000}{80} \times 100$ =37500

$\displaystyle\, \frac{24000}{15} \times 100$ =160000

$\displaystyle\, \frac{27000}{45} \times 100$ =60000

$\displaystyle\, \frac{80000}{25} \times 100$ =320000

Hence, Q has minimum number of film watchers.

0%
$18$
0%
$5$
0%
$20$
0%
$25$

Explanation

$\cfrac{72-54}{72} \times 100 = \cfrac{18}{72} \times 100 = 25\%$

The following pie chart shows the result of a survey among

$100$ students regarding their subject preference.
The number of students who prefer Psychology exceeds that of the students who prefer Social Science by

0%
$60$
0%
$10$
0%
$20$
0%
$40$

Explanation

The number of students preferring Psychology

$=\dfrac{216}{360}\times 100 = 60$

The number of students who prefer Social Science

$=\dfrac{72}{360}\times 100 = 20$

The number of students who prefer Psychology is more than the students who prefer Social Science

$=60 - 20 = 40$

Choose the correct answer from the alternatives given.
Study the following pie chart carefully to answer the questions that follow.
The sectorial angle made by the expenses of the family on education.

0%
$45^{\circ}$
0%
$60^{\circ}$
0%
$90^{\circ}$
0%
$120^{\circ}$

Explanation

% Expenses on Education = 25% Sectorial angle made by the expenses of family on Education

$= \, \dfrac{25}{100} \, \times \, 360^{\circ} \, = \, 90^{\circ}$

The following data gives the distribution of monthly expenses under different heads.

Type of Commodity	Expenditure (in rupees)
Food	$300$
Rent	$200$
Clothes	$125$
Education	$110$
Miscellaneous	$75$
Savings	$90$

A pie chart is drawn for the above data, the angle subtended at the centre for the item 'Rent' will be

0%
$20^{\circ}$
0%
$80^{\circ}$
0%
$85^{\circ}$
0%
$120^{\circ}$

Explanation

$Rs. 900$ sweeps

$\angle 360^{\circ}$

$Re. 1$ sweeps

$\dfrac {360^{\circ}}{900}$

$Rs. 200$ sweeps

$\dfrac {360}{900}\times 200 = 80^{\circ}$ .

What is the sectorial angle corresponding to the money spent by the family in savings, clothing and others together?

0%
$144^{\circ}$
0%
$162^{\circ}$
0%
$108^{\circ}$
0%
$180^{\circ}$

Explanation

$\Rightarrow$ Percentage of money spend in saving

$=15\%$

$\Rightarrow$ Percentage of money spend in clothing

$=10\%$

$\Rightarrow$ Percentage of money spend in other things

$=20\%$

$\Rightarrow$ Total percentage of money spend in saving, clothing and other things

$=15\%+10\%+20\%=45\%$

$\Rightarrow$ The sectorial angle corresponding to money spend in savings, clothing and other together

$=45\% \,of\,360^o$

$=\dfrac{45}{100}\times 360^o$

$=162^o$

If the total amount spent during the year 2010 was Rs. 46000, the amount spent on food, was

0%
$Rs. 2000$
0%
$Rs. 10580$
0%
$Rs. 23000$
0%
$Rs. 2300$

Explanation

: Total amount spent =

$Rs. 46000$
Amount spent on food

$23\%$ of

$46000$

Let

$A$ be the required amount.

$A=\displaystyle \frac{23}{100} \, \times \, 46000$

$= Rs. 10580$
Hence, the amount spent on food is

$Rs. 10580$

Study the pie chart and answer the given questions.
The total expenditure of a company for a particular month is

$Rs.\; 60000$ . The various heads of expenditure I to IV are indicated in a pie chart given below. These heads are:
I. Raw materials
II. Conveyance
III. Electricity
IV. Overhead expenses.
What is the difference in the expenditures of conveyance and electricity?

0%
$Rs.\; 3,000$
0%
$Rs. \;6,000$
0%
$Rs.\; 9,000$
0%
$Rs.\; 12,000$

Explanation

$90^{\circ} - 72^{\circ} =18^{\circ}$

So, we can say that difference in the expenditure incurred on conveyance and electricity is equal to amount corresponding to

$18^\circ.$

$\begin{aligned}{}\frac{{18}}{{360}} \times 100 &= 5\% \\\frac{5}{{100}} \times 60000& =Rs.\; 3000\end{aligned}$

0%
$30^{\circ}$
0%
$72^{\circ}$
0%
$108^{\circ}$
0%
$60^{\circ}$

Explanation

$\Rightarrow$ Percentage of students in

$B.Sc.=30\%$

$\Rightarrow$ Sectorial angle of students in

$B.Sc=\%\,of\,B.Sc.\,students\times 360^o$

$=30\%\times 360^o$

$=\dfrac{30}{100}\times 360^o$

$=108^o$

Choose the correct answers from the alternatives given.

A family spends Rs.

$6000$ p.m to meet the monthly expenditure. The expenditure has been shown in the given pie diagram. The miscellaneous expenditure (in Rs.) is

0%
$2000$
0%
$1500$
0%

${ 360 }^{ o }$ is equivalent to

$6000$ p.m

$\therefore$

${1}^{o}$ is equivalent

$\cfrac { 6000 }{ 360 }$

$\Rightarrow { 120 }^{ o }$ (corresponding to misc.)

$=\cfrac { 6000 }{ 360 } \times 120=2000Rs.$

In a test in Mathematics,

$20$ % of the students obtained "first class". If the data are represented by a Pie-Chart, what is the central angle corresponding to "first class"?

0%
${20}^{o}$
0%
${36}^{o}$
0%
${72}^{o}$
0%
${144}^{o}$

Explanation

The Pie Chart is a part of Circle,

Total Central Angle is

$360^o$

So,

$360^o=100\%$

$\Rightarrow \dfrac{360^o}{100}=1\%$

So,

$20\%$

$=\dfrac{360^o}{100}\times 20=72^o$
