Some sample examples on pictographs or pictorial representation are shown, how the objects are used to give information regarding mathematical data.
Read the pictograph and gather the information from the different objects whose pictures or symbols are used in the table.
Some solved examples on picture-graph:
Let us now learn how to understand a pictograph with the following example.
1. Number of red colored boxes sold by William, a shopkeeper, in six days of a week. See the picture graph or pictograph to answer the questions.
Information gathered from the above table:
(i) Number of red boxes sold:
Monday – 4, Tuesday – 2, Wednesday – 3, Thursday – 5, Friday – 8, Saturday – 1
Therefore, sale during the week = 23
(ii) Lowest sale – on Saturday, only 1 box
was sold.
Maximum sale on Friday is 8 boxes were sold.
We can easily get more information by observing this picture-graph.
2. Number of illiterate children of 5 small towns, Melrose, Marengo, Midway, Parral and Rushville. See the picture graph or pictograph to answer the questions.
Information gathered from the above table:
(i) Number of illiterate children of different small towns:
Melrose - 5, Marengo - 4, Midway - 7, Parral - 3 and Rushville - 2
(ii) Total number of illiterate = 21
3. Information about 300 children of a school who come to school by different modes of transportation.
See the picture graph or pictograph to answer the questions.
Information gathered from the above table:
(i) Number of students going to school by different modes of transportation:
Auto-rickshaw = 6 × 10 = 60, Car = 4 × 10 = 40, Bicycle = 7 × 10 = 70, Bus = 10 × 10 = 100, On foot = 3 × 10 = 30
(ii) Total number = 60 + 40 + 70 + 100 + 30 = 300
The above explanation on the examples of pictographs or pictorial representation will help us to solve different types of questions on pictograph.

Representation of the given information by drawing pictures is called pictograph.
Read the given pictograph and answer the following questions.
5. The following pictograph shows the games liked by the students of a class.
Use this pictograph to answer the following questions.
(i)) How many students like playing hockey?
(ii) Which is the least liked game?

(iv) Calculate the total number of students.
(v) How many fewer students like football than badminton?
Solution:
(i) 30 students
(ii) Football
(iii) 40 students
(iv) Hockey = 6 × 5=30 students.
Football = 5 × 5 = 25 students.
Cricket = 8 × 5 = 40 students.
Badminton = 9 × 5 = 45 students.
Total Students = 30 + 25 + 40 + 45 = 140 students.
(v) 45 - 25 = 20 students.
