NCERT Solutions for Class 4th Maths Chapter 14 Collecting data from your own class — Activity — Chess or Cricket
Book page 207 Updated on2026-09-19
Q1.
Find out from your classmates how many of them play only chess, only cricket, both or neither.
Answer
The empty space the book leaves on page 207 for your own record.
This is your own survey, so your numbers will be your class’s numbers. Do it like this.
Frame one clear question: “Which of these do you play — chess, cricket, both, or neither?”
Make four headings on a page: Only chess, Only cricket, Both, Neither.
Ask every classmate one by one. Put one mark under the heading they choose.
Also write B for a boy and G for a girl beside each mark, because two questions later ask about boys and girls.
At the end, count the marks under each heading.
What a correct result looks like: each classmate is counted exactly once, so the four counts added together must equal the number of children in your class.
only chess + only cricket + both + neither = number of children in the class
Sample answer: in a class of 30 children — only chess 6, only cricket 12, both 8, neither 4.
6 + 12 + 8 + 4 = 30 ✔
Why it happens: The four groups do not overlap. A child who plays both is counted in “Both” only, not again in “only chess”.
Tip: Write the marks as you ask, not from memory. That is exactly what Anjali and Rohan did with the clipboard.
Q2.
Now let us organise the above data in the table.
Nature of Games
No. of Girls
No. of Boys
Chess but not Cricket
Cricket but not Chess
Both
Neither
The table on page 207 that you have to fill with your own class data.
Answer
Nature of Games
No. of Girls
No. of Boys
Chess but not Cricket
Cricket but not Chess
Both
Neither
The table on page 207 that you have to fill with your own class data.
Move the marks you collected into the table. Girls go in one column and boys in the other.
Sample answer (for the class of 30 used above — put your own counts in your book):
Nature of Games
No. of Girls
No. of Boys
Chess but not Cricket
4
2
Cricket but not Chess
3
9
Both
4
4
Neither
3
1
Total
14
16
14 girls + 16 boys = 30 children ✔
Why it happens: The table only re-arranges the marks; it does not change them. So the table total must be the same as the class strength.
Q3.
Who plays Chess the most? _______ (Boys/Girls)
Nature of Games
No. of Girls

Answer

The table on page 207 that you have to fill with your own class data.
A child plays chess if they are in the “Chess but not Cricket” row or in the “Both” row. Add those two rows for each column.
Girls who play chess = (chess only) + (both) Boys who play chess = (chess only) + (both)
Whichever total is bigger is your answer. Write Boys or Girls accordingly.
Sample answer (from the sample table above):
Girls = 4 + 4 = 8 Boys = 2 + 4 = 6 8 > 6
In that class, Girls play chess the most.
Why it happens: “Both” children play chess too, so they must be added in. Leaving them out would give a wrong answer.
Q4.
Who plays Cricket the most? _______ (Boys/Girls)
Nature of Games
No. of Girls
No. of Boys
Chess but not Cricket

In the same way, a child plays cricket if they are in the “Cricket but not Chess” row or in the “Both” row.
Girls who play cricket = (cricket only) + (both) Boys who play cricket = (cricket only) + (both)
Sample answer (from the sample table above):
Girls = 3 + 4 = 7 Boys = 9 + 4 = 13 13 > 7
In that class, Boys play cricket the most.
Why it happens: The “Both” row belongs to chess and to cricket, so it is counted once in each of these two answers.
Tip: Your class may give the opposite answer. That is fine — data answers change with the data.
Q5.
How many children play both types of games? _______
Nature of Games
No. of Girls
No. of Boys
Chess but not Cricket
Cricket but not Chess
Both
Neither
The table on page 207 that you have to fill with your own class data.
Answer
Nature of Games
No. of Girls
No. of Boys

Cricket but not Chess

Neither
The table on page 207 that you have to fill with your own class data.
This one is read straight from the table. Add the two numbers in the “Both” row.
children who play both = girls in “Both” + boys in “Both”
Sample answer (from the sample table above):
4 + 4 = 8 children
Why it happens: The “Both” row already holds exactly the children who play chess as well as cricket, so no other row is needed.
