Q5 (i) The number of hours for which students of a particular class watched television during holidays is shown through the given graph. Answer the following.

For how many hours did the maximum number of students watch TV?

1643185499893

Answer: (i) From the graph we observed that the maximum number of students (32) watch TV for 4-5 hours.

Q5 (ii) The number of hours for which students of a particular class watched television during holidays is shown through the given graph. Answer the following.

How many students watched TV for less than 4 hours?

1643185546249

Answer: (ii) 34 students watched TV for less than 4 hours.
The number of students who watched TV for less than 4 hours = sum of the students who watched TV for (3–4hours) + (2–3hours) + (1–2hours.)
So, the total number of students = 4 + 8 + 22 = 34

Q5 (iii) The number of hours for which students of a particular class watched television during holidays is shown through the given graph. Answer the following.

How many students spent more than 5 hours in watching TV?

1643185585775

Answer: (iii) 14 students spent more than 5 hours in watching TV.
The number of students who watched TV for >5 hours = number of students who watched TV for (5 – 6 hours) + (6 – 7 hours).
So the no. of students = 8 + 6 = 14

Q1 A survey was made to find the type of music that a certain group of young people liked in a city. Adjoining pie chart shows the findings of this survey. From this pie chart answer the following:

(i) If 20 people liked classical music, how many young people were surveyed?

(ii) Which type of music is liked by the maximum number of people?

(iii) If a cassette company were to make 1000 CD’s, how many of each type would they make?

1643185766828

Answer:

1643185776886

(i)If 20 people liked classical music

Total number of people = $(100\times 20)\div 10$ = $200$ people.

(ii) Maximum number of people light music i.e. $40 \%$ .

(iii) If a cassette company were to make 1000 CD’s, then

Light music CD's = $( 40\times 1000) \div 100\:\:=400$

Folk music CD's = $\left ( 30\times 1000 \right )\div 100\:\:=300$

Classical music CD's = $\left ( 10\times 1000 \right )\div 100\:\:=100$

Semi classical music CD's = $\left ( 20\times 1000 \right )\div 100\:\:=200$

Q2 A group of 360 people were asked to vote for their favourite season from the three seasons rainy, winter and summer.

1596116645481

(i) Which season got the most votes?

(iii) Draw a pie chart to show this information.

Answer:

1596116746260

(i) Winter season got the most votes.

(ii) Total Votes = 90+120+150 = 360

central angle of summer = $(90\degree\times 360\degree)\div 360\degree$ = $90\degree$

central angle of rainy = $(120\degree\times 360\degree)\div 360\degree$ = $120\degree$

central angle of winter = $(150\degree\times 360\degree)\div 360\degree$ = $150\degree$

(iii)

Q4 The adjoining pie chart gives the marks scored in an examination by a student in Hindi, English, Mathematics, Social Science and Science. If the total marks obtained by the students were $540$ , answer the following questions.

1643185884248

(i) In which subject did the student score 105 marks?

( Hint: for $540$ marks, the central angle $=360^{\circ}$ . So, for $105$ marks, what is the central angle?)

Answer:

subject	central angle	marks obtained
mathematics	$90\degree$	$(90\degree\times 540)\div 360 = 135$
science	$80\degree$	$(80\degree\times 540)\div 360 = 120$
social science	$65\degree$	$(65\degree\times 540)\div 360 = 97.5$
english	$55\degree$	$(55\degree\times 540)\div 360 = 82.5$
hindi	$70\degree$	$(70\degree\times 540)\div 360 = 105$

(i) In hindi subject the student score 105 marks.

Q4 (ii) The adjoining pie chart gives the marks scored in an examination by a student in Hindi, English, Mathematics, Social Science and Science. If the total marks obtained by the students were $540$ , answer the following questions.

How many more marks were obtained by the student in Mathematics than in Hindi?

1643185910792

Answer:

subject	central angle	marks obtained
mathematics	$90\degree$	$(90\degree\times 540)\div 360 = 135$
science	$80\degree$	$(80\degree\times 540)\div 360 = 120$
social science	$65\degree$	$(65\degree\times 540)\div 360 = 97.5$
english	$55\degree$	$(55\degree\times 540)\div 360 = 82.5$
hindi	$70\degree$	$(70\degree\times 540)\div 360 = 105$

(ii) $135-105=30$

Hence, 30 more marks were obtained by the student in Mathematics than in Hindi.

Examine whether the sum of the marks obtained in Social Science and Mathematics is more than that in Science and Hindi.

(Hint: Just study the central angles).

1643185937900

Answer:

subject	central angle	marks obtained
mathematics	$90\degree$	$(90\degree\times 540)\div 360 = 135$
science	$80\degree$	$(80\degree\times 540)\div 360 = 120$
social science	$65\degree$	$(65\degree\times 540)\div 360 = 97.5$
english	$55\degree$	$(55\degree\times 540)\div 360 = 82.5$
hindi	$70\degree$	$(70\degree\times 540)\div 360 = 105$

(iii) the sum of the marks obtained in Social Science and Mathematics = $97.5+135=232.5$

the sum of the marks obtained in Science and Hindi = $120+105=225$

Yes, the sum of the marks obtained in Social Science and Mathematics is more than that in Science and Hindi.

$=\frac{4}{10}=0.4$

(iv) 1 digit numbers = 1,2,3,4,5,6,7,8,9 = 9 numbers

the probability of getting a 1 digit number

$=\frac{9}{10}=0.9$

Q5 If you have a spinning wheel with 3 green sectors, 1 blue sector and 1 red sector, what is the probability of getting a green sector? What is the probability of getting a non blue sector?

Answer:

Total sectors = 5

the probability of getting a green sector

$=\frac{3}{5}$

Non blue sector = 5-1 = 4

probability of getting a non blue sector

$=\frac{4}{5}$

Q6 Find the probabilities of the events given in Question 2.

When a die is thrown, list the outcomes of an event of getting

(i) (a) a prime number

(b) not a prime number.

(ii) (a) a number greater than 5

(b) a number not greater than 5.

Answer:

Total outcomes = 6

6.(i) (a) prime numbers = 2,3,5 = 3 numbers

probability of prime number

$=\frac{3}{6}=\frac{1}{2}$

(b) non prime numbers = 1,4,6 = 3 numbers

probability of non prime number

$=\frac{3}{6}=\frac{1}{2}$

(ii) (a) number greater than 5 = 6 = 1 number only

probability of getting number greater than 5

$=\frac{1}{6}$

(b) number not greater than 5 = 1,2,3,4,5 = 5 numbers.

probability of getting number not greater than 5

$=\frac{5}{6}$
