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.

Solution:
(a) Class 8
(b) Number of Girls in class 6 = 4 × 4 = 16
Number of Girls in class 5 = 4 × 3.5 = 14
Hence difference = 16 – 14 = 2
(c) Five full symbols of a girl
(d) 3 × 4 = 12 girls.

Question 8. Mudhol Hounds (a type of breed of Indian dogs) are largely found in North Karnataka’s Bagalkote and Vijaypura districts. The government took the 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 is as follows-
Village A: 18, Village B: 36, Village C: 12, Village D: 48, Village E: 18, Village F: 24

Question 11. The number of tigers in India went down drastically between 1900 and 1970. Project Tiger was launched in 1973 to track and protect tigers in India. Starting in 2006, the exact number of tigers in India was tracked. Shagufta and Divya looked up information about the number of tigers in India between 2006 and 2022 in 4-year intervals. They prepared a frequency table for this data and a bar graph to present this data, but there are a few mistakes in the graph. Can you find those mistakes and fix them?

Solution:
Yes, there are a few mistakes in the graph.

1. No. of tigers in 2006 was 1400 but shown less in the graph.

2. No. of tigers in 2014 was 2200 but shown more in the graph.

3. No. of tigers in 2018 was 3000 but shown less in the graph.

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?
Solution:Graph with vertical bars. Vertical graphs are like pillars and show a much better presentation of the person’s height.

Question 2. If you were making a table of the longest rivers on each continent and their lengths, would you prefer to use a bar graph with vertical bars or horizontal bars? Why? Try finding out this information, and then make the corresponding table and bar graph! Which continents have the, longest rivers?
Solution: Graph with horizontal bars, because rivers flow on land horizontally.
