Data Handling Class 6 Worksheet Maths Chapter 4

Q1: The pictograph shows how many snowballs each child made. Use the pictograph to answer the given questions. 

(i) How many snowballs did Alfredo make?
Ans: There are 3 pictures in front of Alfredo. 1 snowflake represents 4 snowballs made.
So, Alfredo made 3x4 = 12 snowballs.

(ii) How many snowballs did Aaron make?
Ans: There are 2 pictures in front of Aaron. 1 snowflake represents 4 snowballs made.
So, Aaron made 2x4 = 8 snowballs. 

(iii) Name two people who made the same number of snowballs.
Ans: Anna and Bailey made the same number of snowballs.
We can simply look at the number of snowflakes in front of each name and see that Anna and Bailey have same number of snowflakes drawn in front of their names.
There are 7 snowflakes which means 7x4 = 28. So, Anna and Bailey, both of them, made 28 snowballs each.

(iv) How many more snowballs did Bailey make than Adeline?
Ans: Bailey made 28 snowballs where as Adeline made 20 snowballs (5x4 = 20)
28- 20 = 8
Bailey made 8 more snowballs than Adeline. 

(v) How many more snowballs did Alexander make than Adora?
Ans: Alexander : 8 x 4 = 32 snowballs
Adora: 4 x 4 = 16
32- 16 = 16
Alexander made 16 more snowballs than Adora.

Q2: Following are the marks obtained by 72 students in Geography. Arrange these marks in a table using tally marks.

(a) students obtained more than 6 marks. 
(b) students obtained marks equal to or below 2. 

Ans: 
Step 1: To count the marks obtained by the students, look at the following tally table:

Step 2: Number of students who scored more than 6 marks Or, the number of students who scored marks 7, 8, 9 = 11 + 9 + 10 = 30 students 

Step 3: Number of students who scored marks equal or less than 2 Or, the number of students who scored marks 2 = 10 = 10 students

Q7: The tally chart shows the items sold during the weekends. Use the information from the tally chart to answer the questions. 

Find the following: 
(a) The sale of is maximum. 
(b) Fried rice were sold in all. 

Ans: 
Step 1: First, let us count the tally marks for each item to find the exact number 

Step 2: Here, we notice that,

Step 3:  (b) Number of Fried rice sold in all = 12 

Q8: The following pictograph shows the number of pears in 6 bags 

 
Find the following. 
(a) Bag with the maximum number of pears. 
(b) Bag with the minimum number of pears. 
(c) Total number of pears in all the bags. 

Ans: 
(a) 3 and 4
(b) 2 and 6
(c) 24 

Step 1 (a) It is clear from the given pictograph that there are 6 pears in the bags 3 and 4. This is the maximum number of pears in all the bags. Therefore, we can say that the bags 3,4 have the maximum number of pears.
Step 2 (b) It is clear from the given pictograph that there are 2 pears in the bags 2 and 6. This is the minimum number of pears in all the bags. Therefore, we can say that the bags 2,6 have the minimum number of pears.
Step 3 (c) Total number of pears in all the bags = Sum of the pears in all the 6 bags = 3 + 2 + 6 + 6 + 5 + 2 = 24 pears
