Question 1.
How many total cars passed through the crossing between 6 am and noon?

Solution:
Total number of cars which passed through the crossing between 6 am and noon = 150 + 1200 + 1000 + 820 + 700 + 600 = 4470 (Refer the bar graph on page 87)

Question 2.
Why do you think so little traffic occurred during the hour of 6-7 am, as compared to the other hours from 7 am-noon?
Solution:
During 6-7 am time duration, little traffic occured as compared to other hours from 7 am-noon, because during 6-7 am, there were less people going to their work.

Question 3.
Why do you think the traffic was the heaviest between 7 am and 8 am?
Solution:
7-8 am is the hour when the maximum number of factory officers and workers use their cars and parents use their cars to drop their children at school.

Question 4.
Why do you think the traffic was lesser and lesser each hour after 8 am until noon?
Solution:
Because, most of the schools start at 8 am – and many factories also start at 8 am and hence less traffic between 8 am-9 am. Most offices start at 9 am and shops start at 10 am and hence less traffic between 9 am-10 am.

(c) What caught your attention in this table?
(d) In how many matches has Bumrah taken 4 wickets?
(e) Mayank says “If we want to know the total number of wickets he has taken in his last 30 matches, we have to add the numbers 0, 1, 2, 3 …, up to 7.” Can Mayank get the total number of wickets taken in this way? Why?
(f) How would you correctly figure out the total number of wickets taken by Bumrah in his last 30 matches, using this table?
Answer:
(a) This table shows a frequency distribution of data on the number of wickets taken by Jaspreet Bumrah in his last 30 matches.
(b) Number of wickets taken by Jaspreet Bumrah in his last 30 matches.
(c) The thing that caught my attention is that Jaspreet Bumrah has taken 3 wickets in most of his matches.
(d) In 3 matches Bumrah has taken 4 wickets.
(e) No, Mayank cannot get the total number of wickets just by adding the numbers 0, 1, 2, 3…up to 7 because he needs to multiply the number by its corresponding frequency first.
(f) By multiplying the number of wickets with its frequency and then adding the product.

Question 4.

The following pictograph shows the number of tractors in five different villages.

Observe the pictograph and answer the following questions—
(a) Which village has the smallest number of tractors?
Solution:
Village D has the smallest number of tractors.

(b) Which village has the most tractors?
Solution:
Village C has the most tractors.

(c) How many more tractors does Village C have than Village B?
Solution:
Number of tractors village C has = 8
Number of tractors village B has = 5
Difference = 8 – 5 = 3
So, village C has 3 more tractors than village B.

(d) Komal says, “Village D has half the number of tractors as Village E.” Is she right?
Solution:
Number of tractors village D has = 3
Number of tractors village E has = 6
Clearly, village D has half the number of tractors as village E.
Hence, Komal is right.

Question 5.
The number of girl students in each class of a school is depicted by a pictograph:

Observe this pictograph and answer the following questions:
(a) Which class has the least number of girl students?
Solution:
Class 8 has the least number of girl students.

(b) What is the difference between the number of girls in Class 5 and 6?
Solution:
Number of girls in class 5 = 4 + 4 + 2 = 10
Number of girls in class 6 = 4 + 4 + 4 + 4= 16
∴ Difference = 16 – 10 = 6

(c) If 2 more girls were admitted in Class 2, how would the graph change?
Solution:
Number of girls in class 2 = 4 + 4 + 4 + 4 + 2 = 18
If 2 more girls are added, then,
Number of girls in class 2 = 18 + 2 = 20
Therefore, new graph would be:

(d) How many girls are there in Class 7?
Solution:
Number of girls in class 7 = 4 + 4 + 4 = 12

Question 6.
Mudhol Hounds (a type of breed of Indian dogs) are largely found in North Karnataka’s Bagalkote and Vijaypura districts. The government took an initiative to protect this breed by providing support to those who adopted these dogs. Due to this initiative, the number of these dogs increased. The number of Mudhol dogs in six villages of Karnataka are as follows
Village A: 18, Village B : 36, Village C : 12, Village D : 48, Village E : 18, Village F: 24
Prepare a pictograph and answer the following questions:
(i) What will be a useful scale or key to draw this pictograph?
(ii) How many symbols will you use to represent the dogs in village 6?
(iii) Kamini said that the number of dogs in village B and village D together will be more than the number of these dogs in the other 4 villages. Is she right? Give reasons for your response.
Solution:
(i) A useful scale would be 1 symbol = 6 dogs.
This scale is a good choice because it divides evenly into the numbers provided (e.g. 18 dogs would be 3 symbols, 36 dogs would be 6 symbols)

(ii) Since, each symbol represents 6 dogs.
∴ Village B has 36 dogs.
∴ 

36

6

 =6 symbols 6
H Hence, 6 symbols will be used to represent the dogs in village B.

(iii) Yes, Kamini is correct. The combined total number of dogs in village B and village D is (36 + 48) = 84 dogs.
∴ The total for other four villages is 72 dogs. Therefore, 84 is greater than 72.
So, Kamini is right.

Question 7.
Students and teachers of a primary school decided to plant tree saplings in the school campus and in the surrounding village during the first week of July. Details of the saplings they planted are as follows:

(a) The total number of saplings planted on Wednesday and Thursday is _________.
(b) The total number of saplings planted during the whole week is _________.
(c) The greatest number of saplings were planted on _________
and the least number of saplings were planted on _________.
Why do you think that is the case? Why were more saplings planted on certain days of the week and less on others? Can you think of possible explanations or reasons? How could you try and figure out whether your explanations are correct?
Solution:
(a) The total number of saplings planted on Wednesday and Thursday is 30 + 40 = 70.
(b) The total number of saplings planted during the whole week is
52 + 40 + 30 + 40 + 50 + 60 + 40
= 312
(c) Do it yourself.

4.5 Artistic and Aesthetic Considerations Figure it Out (Page 103)

Question 1.
If you wanted to visually represent the data of the heights of the tallest persons in each class in your school, would you use a graph with vertical bars or horizontal bars? Why?
Answer:

I would use a graph with vertical bars to represent the heights of the tallest persons in each class.

Why?

Heights are naturally measured upwards from the ground.

Vertical bars visually suggest an increase in height, making it easier to compare who is taller or shorter.

A column graph (vertical bars) clearly shows the difference in height, as each bar rises according to the value.
