15. Data Through Pictures

Solutions to all data handling questions on tables, pictographs and bar graphs. CBSE / NCERT Class 5 Maths Mela.

Child TV Reporter

1Samaira and Kabir collected data from 35 friends. Complete the table.

No. of Hours Spent Watching TV	No. of Children
12 hour	9
1 hour	13
112 hours	7
2 hours	3
More than 2 hours	3
Total	35

2Look at the table and answer the following questions.

1. Children who watch TV for more than half an hour = 35 − 9 = 26

2. Children who watch TV for less than two hours = 9 + 13 + 7 = 29

3. The number of children who watch TV for more than two hours is 3.

4. More children watch TV for two hours than half an hour. — False (3 children watch for 2 hours, but 9 watch for half an hour.)

Yes, watching TV for a long time can harm our eyes. We should take breaks and play outdoors.

Stock-Taking in a Shop

1Joseph Uncle finds it difficult to draw a picture for every item. Suggest some ways to him.

He can use one picture to stand for many items, like 1 picture = 5 items or 1 picture = 10 items. This is called using a scale.

2Answer the questions based on Dipesh’s pictograph (1 icon = 5 items).

(1) Toys: 8 icons × 5 = 40 toys

(2) Board games: 10 icons × 5 = 50 board games

(3) Sports items: 12 icons × 5 = 60. Total play items = 40 + 50 + 60 = 150

3Is there any other scale that you can use to make the pictograph?

Yes. We can use 1 icon = 10 items.

Then: Toys — 4 icons, Board games — 5 icons, Sports items — 6 icons.

Two-wheelers on the Road

1Observe the pictograph (1 icon = 3 two-wheelers) and answer the questions.

Monday: 8 icons = 24
Wednesday: 4 icons = 12
Friday: 12 icons = 36

1. Friday had the most two-wheelers.

2. Total = 24 + 12 + 36 = 72 two-wheelers

3. Wednesday had 24 − 12 = 12 fewer two-wheelers than Monday.

4. Friday had 36 − 12 = 24 more two-wheelers than Wednesday.

5. With 1 icon = 6 two-wheelers: Monday — 4 icons, Wednesday — 2 icons, Friday — 6 icons.

Recording a Day

1How is Sheela’s recording different from Raman’s recording?

Raman used pictures (1 picture = 1 hour) in a table. This is a pictograph.

Sheela drew a bar for each activity. The height of the bar shows the number of hours. This is a bar graph.

2Observe Raman’s and Sheela’s routines and answer the questions.

Activity	Raman (hours)	Sheela (hours)
Sleeping	9	8
Time in school	6	7
Studying	2	4
Eating and playing	6	3
Other activities	1	2

1. Raman’s routine shows more time spent on sleeping (9 hours).

2. Sheela spends more hours in school (7 hours).

3. Sheela spends 4 − 2 = 2 hours more studying than Raman.

4. No. They do not spend the same time on any activity.

5. Sheela’s routine is more balanced. She gets enough sleep and spends time on studying as well as playing. Raman studies only 2 hours but plays for 6 hours.

Day in My Life

1Record your daily routine and make a bar graph.

Activity. Example: Sleeping — 9 hours, Time in school — 6 hours, Studying — 2 hours, Eating — 2 hours. Draw one bar for each activity. The height of each bar should match the number of hours.

Whose Index Finger is Longer?

1Paste the paper strips of your friends’ index fingers and answer the questions.

Activity. Example answers: 1. Riya’s index finger is the longest. 2. The longest index finger is 7 cm. 3. The smallest index finger is 5 cm long. 4. It belongs to Aman.

Food Wastage in the School Canteen

1What do you think about food wastage? How can we reduce it? What can we do with leftover food?

Wasting food is wrong. Many people do not get enough food.

We can reduce wastage by taking only as much food as we can eat. We can share leftover food with the needy, feed animals, or use it to make compost.

2Observe the graph and answer the questions.

Food wasted: Sandwich (Monday) 5 kg, Paratha (Tuesday) 6 kg, Khichdi (Wednesday) 8 kg, Puri-Sabzi (Thursday) 7 kg, Idli-Sambar (Friday) 4 kg.

1. Khichdi had the highest wastage (8 kg).

2. Idli-Sambar had the least wastage (4 kg).

3. Total = 5 + 6 + 8 + 7 + 4 = 30 kg

4. Children who could have been fed = 30 × 3 = 90 children

5. Friday had less food wastage than Wednesday. (Other answers are possible, like Monday and Tuesday.)

6. Khichdi is likely to be wasted the most.
