Exercise 33(B)
1. The sale of vehicles, in a particular city, during the first six months of the year 2016 is shown below:
Month Jan Feb March April May June
Number of 3000 2500 4000 1000 1500 3500
vehicles sold
Draw a pictograph to represent the above data
Solution:
Let us consider one
= 500 vehicles sold
Hence, the pictograph to represent the data is shown below
2. The following pictograph shows the number of cars sold by four dealers A, B, C and D in a city. Scale:
= 50 cars
Using the pictograph, drawn above, answer the following questions:
(i) How many more cars has dealer A sold as compared to dealer D?
(ii) What is the total number of cars sold by all the dealers?
Solution:
Given
One figure = 50 cars
Hence, cars sold by dealer A and D can be calculated as below
Cars sold by A = 6 × 50
= 300 cars
Cars sold by D = 4 × 50
= 200 cars
Total cars sold by A than D = 300 – 200
= 100
Hence, A sold 100 more cars than D
(ii) Total number of cars = 23
Scale = 50 cars
Hence,
Total number of cars sold by all the dealers can be calculated as below
Total number of cars sold = 23 × 50
= 1150 cars
Hence, total number of cars sold by all the dealers is 1150 cars
3. The following pictograph shows the number of watches manufactured by a factory, in a particular weeks.
Scale:
= 100 watches
Find
(i) on which day were the least number of watches manufactured?
(ii) total number of watches manufactured in the whole week?
Solution:
(i) The day on which the least number of watches are manufactured is Friday
Number of watches manufactured on Friday = 100 × 5
= 500 watches
(ii) Total number of watches manufactured in the whole week can be calculated as below
Total number of watches manufactured = 100 × 42.5
= 4250 watches
4. The number or animals in five villages are as follows:
| Village | A | B | C | D | E |
| No. of animals | 160 | 240 | 180 | 80 | 120 |
Prepare a pictograph of these animals using one symbol to represent 20 animals.
Solution:
Let
represents 20 animals
Hence, the pictograph representing animals in five villages are as follows:
5. The following pictograph shows different subject books which are kept in a school library.
Taking symbol of one book = 50 books, find:
(i) how many History books are there in the library?
(ii) how many Science books are there in the library?
(iii) Which books are maximum in number?
Solution:
(i) Given
One book = 50 books
Hence, total number of History books can be calculated as below
Total number of History books = 50 × 4
= 200 books
Therefore, there are 200 History books in the library
(ii) Given
One book = 50 books
Hence, total number of Science books can be calculated as below
Total number of Science books = 50 × 5.5
= 275 books
Therefore, there are 275 Science books in the library
(iii) From the given pictograph, English books are maximum in number in the library
Given
One book = 50 books
Hence, total number of English books can be calculated as below
Total number of English books = 50 × 9
= 450 books
Therefore, there are 450 English books in the library
