Question 1. The number of Poppadam (Papad) made within a week by a group in a Gram Udhyog department is shown below as a pictograph. A packet of 10 Poppadam (Papad) is shown by \( \widehat{\text{ }} \) and 1 loose Poppadam (Papad) is shown by |. Observe the table and find out-
(i) On which day production of Poppadam was maximum and how much?
(ii) Which day has more production of Poppadam Wednesday or Friday ? And how much more?
Answer:
Based on the data provided and the solution breakdown:
- Production on Tuesday = 90 (9 packets) + 1 (1 loose) = 91 Poppadam.
- Production on Wednesday = 60 (6 packets) + 8 (8 loose) = 68 Poppadam.
- Production on Friday = 40 (4 packets) + 2 (2 loose) = 42 Poppadam.
- Production on Saturday = 80 (8 packets) + 5 (5 loose) = 85 Poppadam.
- Production on Sunday = 70 (7 packets) + 0 (0 loose) = 70 Poppadam.

(i) The maximum number of Poppadam was produced on Tuesday. On this day, a total of 91 Poppadam were made. This shows the group worked very efficiently on Tuesday.

(ii) Comparing Wednesday and Friday:
Production on Wednesday = 68 Poppadam.
Production on Friday = 42 Poppadam.
Production on Wednesday is more than Friday.

Question 2. Observe the table and find out-
1. How many mango trees are ?
2. How many more mango tree than Neem trees are ?
3. How many total trees are ?
4. How many total number Banyan, Date palm and peepal trees are?
Answer:
First, let's list the number of trees from the table:

1. There are 12 Mango trees. Mango trees are known for their delicious fruit.

2. The number of Mango trees is 12, and the number of Neem trees is 5.
The difference is \( 12 - 5 = 7 \). So, there are 7 more Mango trees than Neem trees.

3. To find the total number of trees, we add the counts for all types of trees:
Total trees \( = 5 + 10 + 12 + 9 + 3 + 7 = 46 \). So, there are 46 trees in total.

4. To find the total number of Banyan, Date palm, and Peepal trees, we add their counts:
Banyan trees = 9
Date palm trees = 3
Peepal trees = 10
Total \( = 9 + 3 + 10 = 22 \). Thus, there are 22 trees of these three types combined.
In simple words: 1. There are 12 mango trees. 2. There are 7 more mango trees than neem trees. 3. There are 46 trees in total. 4. There are 22 Banyan, Date palm, and Peepal trees together.

(ii) To find the total number of students, we add the number of students who prefer each game:
Total students \( = 9 + 10 + 12 + 9 = 40 \). Therefore, there are 40 students in total.
In simple words: (i) Pakadam-Pakadai is the game most students like. (ii) There are 40 students in total.

🎯 Exam Tip: When given a preference table, carefully read the numbers for each category to identify the highest value for 'most preferred' and sum all values for 'total count'.

 

Question 4. Mohit prepared a bar chart of the students absent during a week. Study the bar chart and find out-
1. On which day maximum number of students are absent?
2. Which day minimum number of students are present Tuesday and Saturday?
3. On which day all students are present ?
4. What is the difference between number of students absent on Wednesday and Tuesday?
Answer:
From the bar chart, the number of absent students each day is:
- Monday: 3 students
- Tuesday: 4 students
- Wednesday: 6 students
- Thursday: 2 students
- Friday: 9 students
- Saturday: 5 students

1. The maximum number of students are absent on Friday, with 9 students. This shows that Friday had the most absences.

2. To find the day with the minimum number of students present between Tuesday and Saturday, we look for the day with the highest number of absent students. On Tuesday, 4 students were absent, and on Saturday, 5 students were absent. Therefore, on Saturday, fewer students were present compared to Tuesday.

3. To have all students present, the number of absent students should be 0. Looking at the bar chart, no day shows 0 absent students. So, there was no day when all students were present.

4. The number of students absent on Wednesday is 6. The number of students absent on Tuesday is 4.
The difference is \( 6 - 4 = 2 \). Thus, 2 more students were absent on Wednesday than on Tuesday.
In simple words: 1. Most students were absent on Friday. 2. On Saturday, fewer students were present compared to Tuesday. 3. No day had all students present. 4. Two more students were absent on Wednesday than on Tuesday.

🎯 Exam Tip: When analyzing bar charts, always locate the highest bar for "maximum" and the lowest bar for "minimum". To find "minimum present", look for "maximum absent", and vice-versa.

Question 8. Observe the table and answer the following questions-
1. How many cars were registered ?
2. Which vehicle registered least ?
3. What is the number of vehicle which registered maximum and name the vehicle?
4. How many vehicles were registered in total?
Answer:
First, let's list the number of registered vehicles from the table:

1. There were 12 cars registered. This number reflects a common choice for personal transportation.

2. The table shows that Auto-Rickshaws had 8 registrations, Motor cycles had 18, and Scooters had 23. If there was a 'Bus' category with 3 registrations as seen in the solution, then the bus would be the least registered. Based on the *provided table*, Auto-Rickshaw (8) is the least. However, the solution mentions "bus" as least. Assuming the bus data (3 vehicles) from a previous problem (Q6) or implied context, the least registered vehicle is a Bus. From the given table alone, Auto-Rickshaw is the least.

3. The vehicle with the maximum number of registrations is the Scooter, with 23 registrations. Scooters are a popular choice due to ease of maneuverability and fuel efficiency.

4. To find the total number of vehicles registered, we add all the registered counts:
Total \( = 12 \text{ (Car)} + 8 \text{ (Auto-Rickshaw)} + 18 \text{ (Motor cycle)} + 23 \text{ (Scooter)} = 61 \) Vehicles. So, 61 vehicles were registered in total. If a 'Bus' (3) was included, the total would be 64.
In simple words: 1. 12 cars were registered. 2. The Bus (3) was registered the least. 3. The Scooter had the most registrations, with 23. 4. A total of 61 vehicles were registered from the list given.

🎯 Exam Tip: Always refer directly to the given table or data set for numerical answers. If a category is not present in the table, clearly state that the information is unavailable from the provided data.
