Question 1. The names of the heads of some families in a village and the quantity of drinking water their family consumes in one day are given below. Draw a bar graph for this data.
(Scale: On Y axis. 1 cm = 10 liters of water)

Name	Ramesh	Shobha	Ayub	Julie	Rahul
Liters of water Used	30 L	60 L	40 L	50L	55 L

Answer:
ℹ️ चित्र व्याख्या (Diagram Explanation): यह चित्र परिवारों के मुखियाओं द्वारा एक दिन में खपत किए गए पानी की मात्रा (लीटर में) को दर्शाता है। इसमें रमेश, शोभा, अयूब, जूली और राहुल के परिवारों की खपत को दर्शाया गया है, जहां Y-अक्ष पर पानी की मात्रा और X-अक्ष पर परिवारों के मुखियाओं के नाम हैं। पैमाना (Y-अक्ष पर): 1 सेमी = 10 लीटर पानी।In simple words: This question requires you to create a bar graph to visually represent the water consumption data for different families, using the provided scale on the Y-axis. The height of each bar corresponds to the liters of water used by each family.

🎯 Exam Tip: Always label both axes clearly and state the scale used for the bar graph to ensure full marks. Missing labels or an incorrect scale can lead to deductions.

 

Question 2. The names and numbers of animals in a certain zoo are given below. Use the data to make a bar graph. (Scale: On Y axis, 1 cm = 4 animals).

Animals	Deer	Tiger	Monkey	Rabbit	Peacock
Number	20	4	12	16	8

Answer:
ℹ️ चित्र व्याख्या (Diagram Explanation): यह चित्र एक चिड़ियाघर में विभिन्न जानवरों की संख्या को दर्शाता है। इसमें हिरण, बाघ, बंदर, खरगोश और मोर की संख्या को दर्शाया गया है, जहां Y-अक्ष पर जानवरों की संख्या और X-अक्ष पर जानवरों के नाम हैं। पैमाना (Y-अक्ष पर): 1 सेमी = 4 जानवर।In simple words: You need to draw a bar graph where the type of animal is on the X-axis and the number of animals is on the Y-axis. The height of each bar will represent the count of each animal, following the given scale.

🎯 Exam Tip: When choosing a scale, make sure it allows all data points to be represented clearly within the graph space. A poorly chosen scale can make the graph hard to read.

 

Question 3. The table below gives the number of children who took part in the various items of the talent show as part of the annual school gathering. Make a bar graph to show this data.
(Scale: On Y-axis, 1 cm = 4 children)

Number of Children	24	40	16	8	4

Answer:
ℹ️ चित्र व्याख्या (Diagram Explanation): यह चित्र वार्षिक विद्यालय समारोह में विभिन्न कार्यक्रमों (थिएटर, नृत्य, गायन संगीत, वाद्य संगीत, एकांकी) में भाग लेने वाले बच्चों की संख्या को दर्शाता है। इसमें Y-अक्ष पर बच्चों की संख्या और X-अक्ष पर कार्यक्रमों के नाम हैं। पैमाना (Y-अक्ष पर): 1 सेमी = 4 बच्चे।In simple words: Construct a bar graph to show how many children participated in each talent show program. The Y-axis will represent the number of children, and the X-axis will list the programs, with bars drawn according to the given scale.

🎯 Exam Tip: Ensure that the bars in your graph are of equal width and that there is consistent spacing between them. This helps in maintaining clarity and correct representation.

 

Question 4. The number of customers who came to a juice centre during one week is given in the table below. Make two different bar graphs to show this data.
(On Y-axis, 1 cm = 10 customers, 1 cm = 5 customers)

Type of juice	Orange	Pineapple	Apple	Mango	Pomegranate
Number of customers	50	30	25	65	10

Answer:
ℹ️ चित्र व्याख्या (Diagram Explanation): यह चित्र एक जूस सेंटर पर एक सप्ताह में विभिन्न प्रकार के जूस (संतरा, अनानास, सेब, आम, अनार) के लिए ग्राहकों की संख्या को दर्शाता है। इसमें Y-अक्ष पर ग्राहकों की संख्या और X-अक्ष पर जूस के प्रकार हैं। पैमाना (Y-अक्ष पर): 1 सेमी = 10 ग्राहक।
ℹ️ चित्र व्याख्या (Diagram Explanation): यह चित्र एक जूस सेंटर पर एक सप्ताह में विभिन्न प्रकार के जूस (संतरा, अनानास, सेब, आम, अनार) के लिए ग्राहकों की संख्या को दर्शाता है। यह पिछले ग्राफ से भिन्न पैमाने (Y-अक्ष पर): 1 सेमी = 5 ग्राहक का उपयोग करता है।In simple words: For this problem, you need to create two bar graphs from the same data set, each using a different scale for the Y-axis as specified. This demonstrates how varying the scale can change the visual representation of the same data.

🎯 Exam Tip: Pay close attention to the specified scales for each graph. Accurately applying different scales to the same data set is a common assessment point in such questions.

 

Question 5. Students planted trees in 5 villages of Sangli district. Make a bar graph of this data.
(Scale: On Y-axis, 1 cm = 100 trees).

Name of Place	Dudhgaon	Bagni	Samdoli	Ashta	Kavathepiran
Number of Trees Planted	500	350	600	420	540

Answer:
ℹ️ चित्र व्याख्या (Diagram Explanation): यह चित्र सांगली जिले के 5 गांवों (दूधगांव, बागनी, समडोली, अष्टा, कवठेपीरन) में छात्रों द्वारा लगाए गए पेड़ों की संख्या को दर्शाता है। इसमें Y-अक्ष पर लगाए गए पेड़ों की संख्या और X-अक्ष पर गांवों के नाम हैं। पैमाना (Y-अक्ष पर): 1 सेमी = 100 पेड़।In simple words: Create a bar graph to illustrate the number of trees planted in each of the five villages. The X-axis will represent the villages, and the Y-axis will show the number of trees, scaled such that 1 cm equals 100 trees.

🎯 Exam Tip: When plotting points that are not exact multiples of the scale (e.g., 350, 420, 540 with a scale of 100), estimate their positions accurately between the major grid lines.

 

Question 6. Yashwant gives different amounts of time as shown below, to different exercises he does during the week. Draw a bar graph to show the details of his schedule using an appropriate scale.

Type of exercise	Running	Yogasanas	Cycling	Mountaineering	Badminton
Time	35 minutes	50 minutes	1 hr 10 min	\(1\frac{1}{2}\) hours	45 minutes

Answer:1 hour = 60 minutes
\( \implies \) 1 hour 10 minutes = 1 hour + 10 minutes = 60 minutes + 10 minutes = 70 minutes
\( \implies \) \(1\frac{1}{2}\) hours = 1 hour + \( \frac{1}{2} \) hour = 60 minutes + 30 minutes = 90 minutes The given table can be written as follows:

Type of Exercise	Running	Yogasanas	Cycling	Moutaineering	Badminton
Time	35 minutes	50 minutes	70 minutes	90 minutes	45 minutes

ℹ️ चित्र व्याख्या (Diagram Explanation): यह चित्र यशवंत द्वारा सप्ताह के दौरान विभिन्न व्यायामों (दौड़ना, योगासन, साइकिल चलाना, पर्वतारोहण, बैडमिंटन) पर बिताए गए समय (मिनटों में) को दर्शाता है। इसमें Y-अक्ष पर समय और X-अक्ष पर व्यायाम के प्रकार हैं। पैमाना (Y-अक्ष पर): 1 सेमी = 10 मिनट।In simple words: First, convert all time durations to a single unit (minutes). Then, draw a bar graph with types of exercise on the X-axis and time in minutes on the Y-axis, selecting a suitable scale.

🎯 Exam Tip: Always convert all units to a common base (e.g., minutes) before plotting the data to avoid errors and ensure consistency in your graph.

 

Question 7. Write the names of four of your classmates. Beside each name, write his/her weight in kilograms. Enter this data in a table like the above and make a bar graph.
Answer:

Name of classmates	Rohan	Laxmi	Rakesh	Riya
