Examples of Interpreting Pictographs

Example 1.
The following pictograph shows how many bikes were washed at the washing center of a service station five days a week. One bike represents 6 bikes.

Days of a Week Number of Bikes
Monday bikebikebike
Tuesday bikebike
Wednesday bikebikebikebikebike
Thursday bikebikebikebikebikebike
Friday bikebikebikebike

(i) How many bikes were washed on different days?
(ii) On which day were the maximum number of bikes washed?
(iii) On which day were the minimum numbers of bikes washed?
(iv) How many more bikes were washed on Thursday than Tuesday?
(v) How many total bikes were washed in five days?

Solution:
We can get the information from the given pictograph. From the given information, every bike is equal to the 6 number of bikes.
(i) On Monday, the number of bike images = 3.
Monday 3 x 6 = 18 bikes.
On Tuesday, the number of bike images = 2.
Monday 2 x 6 = 12 bikes.
On Wednesday, the number of bike images = 5.
Monday 5 x 6 = 30 bikes.
On Thursday, the number of bike images = 6.
Monday 6 x 6 = 36 bikes.
On Friday, the number of bike images = 4.
Monday 4 x 6 = 24 bikes.
(ii) On Thursday maximum number of bikes (36) were washed.
(iii) On Tuesday minimum number of cars (12) were washed
(iv) 24 more bikes were washed on Thursday than Tuesday. 36 – 12 = 24 bikes.
(v) 18 bikes + 12 bikes + 30 bikes + 36 bikes + 24 bikes = 120 bikes

Example 2.
There is a pictograph showing rainfall of different cities named (P, Q, R, S, T, and U) during the current year. Answer the following questions on the basis of this pictograph. One rainfall represents 20 cm of rainfall.

City Rainfall in cm
P rainfallrainfallrainfallrainfallrainfall
Q rainfallrainfallrainfallrainfall
R rainfallrainfall
S rainfallrainfallrainfallrainfallrainfallrainfall
T rainfallrainfallrainfallrainfallrainfallrainfallrainfallrainfallrainfallrainfall
U rainfallrainfallrainfall

(i) Give the information regarding rainfall in cities P, Q, R, S, T, and U in cm.
(ii) In which city was there maximum rainfall?
(iii) In which city was there minimum rainfall?
(iv) City Q recorded how much more rainfall than the city R?
(v) Compare the rainfall between the city S and T.

Solution:
We can get the information from the given pictograph. From the given information, every rainfall in cities is equal to 20 cm of rainfall.
(i) In city P, 5 x 20 = 100 cm
In city Q 4 x 20 = 80 cm
In city R 2 x 20 = 40 cm
In city S 6 x 20 = 120 cm
In city T 10 x 20 = 20 cm
In city U 3 x 20 = 60 cm
(ii) Maximum rainfall occurred in city S, i.e., 120 cm.
(iii) Minimum rainfall was in city T that is 20 cm.
(iv) Difference between rainfalls of city Q and R = 80 – 40 = 40 cm. City Q has more rainfall.
(v) The rainfall in city S was 120 cm, and in city T it was 20 cm. So, city S recorded more rainfall than city T.

Example 3.
There is a pictograph showing data of 100 students has been collected, who like different colors. Answer the following questions on the basis of this pictograph. One pictograph is equal to 4 Students.

(i) Give the information regarding the number of students like every color.
(ii) Which is the most liked color by a maximum number of students?
(iii) Which color is less liked by students?
(v) Compare the number of students between the Blue and Yellow Colors.

Solution:
We can get the information from the given pictograph. From the given information, every circle is equal to 4 students.
(i) Black color, 4 x 4 = 16 students
Red color, 2 x 4 = 8 students
Blue color, 8 x 4 = 32 students
Yellow color, 6 x 4 = 24 students.
(ii) Blue color is most liked by many students.
(iii) Red color less liked by students
(iv) The number of students who liked the Blue and Yellow Colors are
Blue = 32 students
Yellow = 24 students.
So, the Blue color has more likes than the Yellow color.
