Chapter 15 of Math Mela is the last chapter of the book. It is about data — the facts and numbers we collect — and about two neat ways to show data as a picture: a pictograph, where a small drawing stands for a number of things, and a bar graph, where a tall bar stands for a big number and a short bar for a small one. Samaira and Kabir count TV hours, Joseph Uncle counts the toys in his shop, Deepti counts scooters on the road, Raman and Sheela record a whole day, and Rani looks at how much food her school throws away.

NCERT Solutions for Class 5 Maths Chapter 15 Data Through Pictures – Questions and Answers
All 46 questions of the chapter (textbook pages 179 – 190) are answered below, in the order of the book – in-text questions, activities and the end-of-chapter exercises. Each answer is written the way you would write it in the exam.
Child TV Reporter — Pages 179–180Samaira and Kabir collect data from 35 friends
Fill in the table.
| No. of Hours Spent Watching TV | No. of Children |
|---|---|
| ½ hour | |
| 1 hour | |
| 1½ hour | |
| 2 hours | |
| More than 2 hours |
The completed table (one mark for each speech bubble):
| No. of Hours Spent Watching TV | No. of Children |
|---|---|
| 1/2 hour | 9 |
| 1 hour | 13 |
| 1 1/2 hour | 7 |
| 2 hours | 3 |
| More than 2 hours | 3 |
| Total | 35 |
= 22 + 7 + 3 + 3
= 29 + 3 + 3
= 32 + 3
= 35 ✓
26 children.
“More than half an hour” means every child except the ones who watch for exactly half an hour.
= 20 + 3 + 3
= 23 + 3
= 26 children
29 children.
- Find the rows that are smaller than 2 hours. They are 1/2 hour, 1 hour and 1 1/2 hour.
- Add those three counts.
= 22 + 7
= 29 children
The number of children who watch TV for more than two hours is 3.
False.
Children who watch for 1/2 hour = 9
3 < 9, so the statement is False
Yes, it can. Watching a screen for a long time without a break tires the eyes.
Stock-Taking in a Shop — Pages 180–181Joseph Uncle’s pictograph, and what a scale does
Ways to show many items with pictures:
- Let one picture stand for many items, e.g. one train = 5 toys. This is using a scale.
- Use a different picture for each kind of item.
- Write the key (what one picture stands for) on the chart.
40 toys.
Each train = 5 toys
Toys = 8 × 5 = 40 toys
50 board games.
Board games = 10 × 5 = 50 board games
150 play items in all.
Board games = 10 × 5 = 50
Sports items = 12 × 5 = 60
Total = 40 + 50 + 60
= 90 + 60
= 150 play items
Yes. A scale of 10 works very well here. All three numbers — 40, 50 and 60 — divide by 10 exactly.
Board games: 50 ÷ 10 = 5 pictures
Sports items: 60 ÷ 10 = 6 pictures
Two-wheelers on the Road — Pages 181–182Deepti’s pictograph, where one icon stands for 3
Friday. On Friday 36 two-wheelers went past Deepti’s house.
Wednesday: 4 scooters = 4 × 3 = 12
Friday: 12 scooters = 12 × 3 = 36
36 is the biggest, so Friday had the most
72 two-wheelers.
- Work out each day. Monday 8 × 3 = 24. Wednesday 4 × 3 = 12. Friday 12 × 3 = 36.
- Add the three days.
= 36 + 36
= 72 two-wheelers
12 fewer.
Wednesday = 4 × 3 = 12
24 − 12 = 12 fewer two-wheelers
24 more.
Wednesday = 4 × 3 = 12
36 − 12 = 24 more two-wheelers
A scale of 6 works well here — 24, 12 and 36 all divide by 6.
Wednesday: 12 ÷ 6 = 2 scooters
Friday: 36 ÷ 6 = 6 scooters
Recording a Day — Pages 182–183Raman’s table and Sheela’s bar graph
| Activities | No. of Hours (□ = 1 hour) |
|---|---|
| Time spent sleeping | |
| Time in school | |
| Time spent studying | |
| Time spent eating and playing | |
| Other activities |
Count the blue squares in each row. One square is one hour.
| Activity | Squares counted | No. of hours |
|---|---|---|
| Time spent sleeping | 9 squares | 9 hours |
| Time in school | 6 squares | 6 hours |
| Time spent studying | 2 squares | 2 hours |
| Time spent eating and playing | 6 squares | 6 hours |
| Other activities | 1 square | 1 hour |
| Total | 24 squares | 24 hours |
= 15 + 2 + 6 + 1
= 17 + 6 + 1
= 23 + 1
= 24 hours ✓
| Activities | No. of Hours (□ = 1 hour) |
|---|---|
| Time spent sleeping | |
| Time in school | |
| Time spent studying | |
| Time spent eating and playing | |
| Other activities |
Raman drew squares, one for each hour. Sheela drew one tall bar for each activity. Both show the same kind of information, but in different ways.
| Raman’s way | Sheela’s way |
|---|---|
| A pictograph — small squares in a row | A bar graph — upright bars |
| You must count the squares one by one | You just read how high the bar reaches |
| Rows go across the page | Bars stand up from a base line |
| Only whole hours can be shown, one square each | A bar can also stop half-way, so half hours can be shown |
| Long rows take a lot of space | A tall bar takes very little space |
| Activities | No. of Hours (□ = 1 hour) |

Raman. He sleeps for 9 hours; Sheela sleeps for 8 hours.
Sheela sleeps 8 hours
9 > 8, so Raman sleeps more
He sleeps 9 − 8 = 1 hour more
| Activities | No. of Hours (□ = 1 hour) |
|---|---|
| Time spent sleeping | |
| Time in school | |
| Time spent studying | |
| Time spent eating and playing | |

Sheela. She spends 7 hours in school; Raman spends 6 hours.
Raman = 6 hours
7 − 6 = 1 hour more for Sheela

|---|---|
| Time spent sleeping | |

4 − 2 = 2 hours more
| Activities | No. of Hours (□ = 1 hour) |
|---|---|
| Time spent sleeping | |
| Time in school | |
| Time spent studying | |
| Time spent eating and playing | |

No. There is no activity on which they spend the same amount of time.
| Activity | Raman | Sheela | Same? |
|---|---|---|---|
| Sleeping | 9 h | 8 h | No |
| Time in school | 6 h | 7 h | No |
| Studying | 2 h | 4 h | No |
| Eating and playing | 6 h | 3 h | No |
| Other activities | 1 h | 2 h | No |
| Total | 24 h | 24 h | Yes — the whole day |
| Activities | No. of Hours (□ = 1 hour) |
|---|---|
| Time spent sleeping | |
| Time in school | |
| Time spent studying | |
| Time spent eating and playing | |
| Other activities |
Sheela’s routine is more balanced.
Sample answer: Sheela sleeps 8 hours, spends 7 hours in school, studies 4 hours and still has 3 hours for eating and playing, so every part of her day gets a fair share. Raman studies only 2 hours but spends 6 hours eating and playing.
Day in My Life — Pages 183–184Record your own 24 hours and draw your own bar graph
| Activity | No. of Hours |
|---|---|
| Sleeping | |
| Time in school | |
| Studying | |
| Eating | |
Your table will show your own day; the hours must add up to 24.
| Activity | No. of Hours |
|---|---|
| Sleeping | 9 hours |
| Time in school | 6 hours |
| Studying (homework at home) | 2 hours |
| Eating | 1 hour 30 minutes |
| Playing | 2 hours |
| Travel, bath, helping at home, TV | 3 hours 30 minutes |
| Total | 24 hours |
1 h 30 min + 2 h + 3 h 30 min = 7 hours
17 + 7 = 24 hours ✓
Turn each row of your table into one bar. Here is the sample table from the last question drawn as a bar graph.
Whose Index Finger is Longer? — Pages 184–185A bar graph made from paper strips
This activity turns real fingers into a real bar graph. The strips are the bars.
The answer comes from your own graph — it is the friend whose strip reaches highest.
Sample answer: In the graph above, Imran has the longest index finger. His strip reaches the line marked 7.
Read the number where the tallest strip stops.
Sample answer: The longest index finger is 7 cm long.
Now find the shortest strip and read its height in the same way.
Sample answer: The smallest index finger is 5 cm long.
Read the name written in the box under the shortest strip.
Sample answer: The smallest index finger, 5 cm long, belongs to Ravi.
Food Wastage in the School Canteen — Pages 185–186Rani’s dining hall notice board and the food wastage bar graph
The notice board in the dining hall says:
- Take all you can eat. Eat all you take. — the rule of the dining hall.
- Yesterday’s food wastage was 13 kg, which could have fed 25 people.
Wasting food is wrong: the food could have fed hungry people, and the farmer’s work, water and fuel are wasted too. We can reduce it by taking small helpings and finishing our plates. Fresh leftover food can be given to people in need; scraps can go to animals or a compost pit.
Khichdi, on Wednesday. 8 kg of khichdi was wasted.
Paratha (Tuesday) = 6 kg
Khichdi (Wednesday) = 8 kg ← highest
Puri-Sabzi (Thursday) = 7 kg
Idli-Sambar (Friday) = 4 kg
Idli-Sambar, on Friday. Only 4 kg was wasted.
4 kg (Idli-Sambar) < 5 kg (Sandwich) < 6 kg (Paratha) < 7 kg (Puri-Sabzi) < 8 kg (Khichdi)
Least = Idli-Sambar, 4 kg
30 kg in the five days.
11 + 8 = 19
19 + 7 = 26
26 + 4 = 30 kg
90 children.
1 kg feeds 3 children
30 kg feeds 30 × 3
= 90 children
- Friday day had less food wastage than Wednesday day. (4 kg < 8 kg)
- Monday day had less food wastage than Thursday day. (5 kg < 7 kg)
- Tuesday day had less food wastage than Wednesday day. (6 kg < 8 kg)
Yes — khichdi is likely to be wasted the most again.
Same children + same dish → khichdi is likely to be wasted most again
True or False — Page 187Reading data straight from a picture of a group of children
True or False: All girls are wearing glasses.
False. Only 3 of the 8 girls are wearing glasses.
Girls wearing glasses = 3
3 ≠ 8, so the statement is False
True. Exactly 10 children are wearing red caps.
Front row caps = 5
5 + 5 = 10 caps
The statement says 10, so it is True
False. The same number of boys and girls are holding books — 7 each.
Girls holding books = 7
7 = 7, so “more boys than girls” is False
The correct sentence is: as many boys as girls are holding books
False. 7 of the 17 children wear glasses, and 7 is less than half of 17.
Children with glasses = 7
Half of 17 = 17 ÷ 2 = 8 1/2
7 < 8 1/2, so less than half wear glasses → False
True. 14 children are holding books and only 10 are wearing caps.
Children wearing caps = 10
14 > 10, so the statement is True
There are 14 − 10 = 4 more book-holders than cap-wearers
True. 4 boys wear glasses and 3 girls wear glasses.
| Boys wearing glasses | Girls wearing glasses |
|---|---|
| Back row: 3 boys | Back row: 1 girl |
| Front row: 1 boy | Front row: 2 girls |
| Total 4 | Total 3 |
True. Six children are wearing a cap and glasses at the same time.
Of these, children who also wear a cap = 3 + 3 = 6
6 is more than zero, so “some” is True
False. There is such a child — the girl standing at the far left of the back row.
| Child with a backpack | Cap? | Book? | All three? |
|---|---|---|---|
| Girl at the far left, back row (with a plait) | Yes | Yes | Yes |
| Girl at the far left, front row (waving) | Yes | No | No |
| Boy in the front row shaking hands | Yes | No | No |
| Boy at the far right, front row | No | No | No |
