The organization of given data can be done using picture symbols to help students in understanding them. Pictographs are the representation of numerical data using picture symbols. With the aim of helping students gain better conceptual knowledge, the faculty at BYJU’S have designed solutions relevant to the latest CBSE guidelines. The solutions are explained in a step-wise manner to make it easier for the students during revision.

1. The sale of electric bulbs on different days of a week is shown below:
Observe the pictograph and answer the following questions:
(i) How many bulbs were sold on Friday?
(ii) On which day maximum number of bulbs were sold?
(iii) If one bulb was sold at the rate of Rs 10, what was the total earning on Sunday?
(iv) Can you find out the total earning of the week?
(v) If one big carton can hold 9 bulbs. How many cartons were needed in the given week, more than 7, more than 8 or more than 9?
Solution:
(i) No. of bulbs shown on Friday = 7
Given that 1 figure = 2 bulbs
So the total number of bulbs sold on Friday = 2 × 7 = 14
Hence, 14 bulbs were sold on Friday.
(ii) From the pictograph, Sunday shows the maximum bulb figures.
Hence, maximum number of bulbs were sold on Sunday.
(iii) No. of bulb figures sold on Sunday = 2 × 9 = 18
Given that Cost of one bulb = Rs 10
So the total earning on Sunday = 10 × 18 = Rs 180
(iv) Total bulb figures shown throughout the week = 6 + 8 + 4 + 5 + 7 + 4 + 9 = 43
So the total number of bulbs = 43 × 2 = 86
Total earning of the week = 10 × 86 = Rs 860
(v) We know that total number of bulbs = 86
It is given that one carton can hold 9 bulbs
So for holding 86 bulbs we require = 86 × 9 = 774 cartons
Hence, more than 9 cartons are needed.
2. A survey was carried out in a certain school to find about the different modes of transport used by students to travel to school each day. 30 students of class VI were interviewed and the data obtained was displayed in the form of a pictographs given below:
Look at the above pictograph and answer the following questions:
(i) How many students are using cycle or walking as a mode of travel?
(ii) Which is most popular mode of travel?
Solution:
(i) From the pictograph we know that
No. of students using cycle = 3
No. of students using walking as a mode of travel = 8
So the number of students using cycle or walking as a mode of travel = 3 + 8 = 11
(ii) From the pictograph we know that maximum number of students use school bus as a mode of travel.
Hence, the most popular mode of travel to school is school bus.
3. The number of girl students in each class of co-ed. Middle school is depicted by the following pictograph:
Observe the above pictograph and answer the following questions:

(ii) Is the number of girls in class VI is less than the number of girls in class V?
(iii) How many girls are there in VII class?
Solution:
Using the above pictograph, we can prepare the chart to find the number of girl students in each class.
It is given that 1 figure = 4 girls
(i) Using the chart we come to know that maximum number of girls are present in Class I.
Hence, Class I has the maximum number of girls.
(ii) Using the chart we come to know that
No. of girls in Class VI = 16
No. of girls in Class V = 10
No, the number of girls in class VI is not less than the number of girls in class V.
(iii) Using the chart we know that 12 girls are there in Class VII.
