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
Selina Solutions Concise Mathematics Class 6 Chapter 33 - 31= 500 vehicles sold

Hence, the pictograph to represent the data is shown below

Selina Solutions Concise Mathematics Class 6 Chapter 33 - 32

2. The following pictograph shows the number of cars sold by four dealers A, B, C and D in a city. Scale:
Selina Solutions Concise Mathematics Class 6 Chapter 33 - 33= 50 cars

Selina Solutions Concise Mathematics Class 6 Chapter 33 - 34

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.

Selina Solutions Concise Mathematics Class 6 Chapter 33 - 35

Scale:
Selina Solutions Concise Mathematics Class 6 Chapter 33 - 36 = 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
Selina Solutions Concise Mathematics Class 6 Chapter 33 - 37represents 20 animals

Hence, the pictograph representing animals in five villages are as follows:

Selina Solutions Concise Mathematics Class 6 Chapter 33 - 38

5. The following pictograph shows different subject books which are kept in a school library.

Selina Solutions Concise Mathematics Class 6 Chapter 33 - 39

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
