## Introduction to Data Interpretation

#### Data Interpretation

Direction: Study the bar diagram and answer the following questions. 1. The difference between average demand and average production of the five companies taken together is

1. According to given bar graph , we have
Total demand of the five companies = 3300 + 1200 + 3000 + 600 + 2500 = 10600
Total production of the five companies = 2200 + 2700 + 1500 + 1800 + 1000 = 9200
Number of given companies = 5

 Required difference = Total demand of the five companies - Total production of the five companies Number of given companies Number of given companies

##### Correct Option: C

According to given bar graph , we have
Total demand of the five companies = 3300 + 1200 + 3000 + 600 + 2500 = 10600
Total production of the five companies = 2200 + 2700 + 1500 + 1800 + 1000 = 9200
Number of given companies = 5

 Required difference = Total demand of the five companies - Total production of the five companies Number of given companies Number of given companies

 Required difference = 10600 - 9200 5 5

Required difference = 2120 – 1840 = 280

1. The ratio of the number of companies having more demand than production to the companies having more production than demand, is

1. From the given bar diagram , we see
Number of companies having more demand than production ( In A, C and E companies ) = 3
Number of companies having more production than demand ( In B and D companies ) = 2
Required ratio = Number of companies having more demand than production : Number of companies having more production than demand

##### Correct Option: D

From the given bar diagram , we see
Number of companies having more demand than production ( In A, C and E companies ) = 3
Number of companies having more production than demand ( In B and D companies ) = 2
Required ratio = Number of companies having more demand than production : Number of companies having more production than demand
Required ratio = 3 : 2

Direction: A watch company produces four different products. The sale of these products in lakhs during 2005 and 2010 are shown in the following bar diagram. Study the graph and answer the questions. 1. The sales have increased by nearly 135% from 2005 to 2010 in the product of

1. As per the given bar graph , we have
The sales of table clock in 2010 = 22.3 lakhs
The sales of table clock in 2005 = 9.5 lakhs
Increase = 22.3 - 9.5 = 12.8

 Percentage increase in the sales of table clocks = Increase × 100 The sales of table clock in 2005

##### Correct Option: A

As per the given bar graph , we have
The sales of table clock in 2010 = 22.3 lakhs
The sales of table clock in 2005 = 9.5 lakhs
Increase = 22.3 - 9.5 = 12.8

 Percentage increase in the sales of table clocks = Increase × 100 The sales of table clock in 2005

 Percentage increase in the sales of table clocks = 12.8 × 100 ≈ 135 9.5

1. During the period 2005-2010, the minimum rate of increase in sales is in the product of

1. Here, decrease is evident from bar diagram.
Wrist watches : 21.3 ⇒ 28.7 lakhs
Table clocks 9.5 ⇒ 22.3 lakhs
Wall clocks 30.7 ⇒ 32.7 lakhs

##### Correct Option: D

Here, decrease is evident from bar diagram.
Wrist watches : 21.3 ⇒ 28.7 lakhs
Table clocks 9.5 ⇒ 22.3 lakhs
Wall clocks 30.7 ⇒ 32.7 lakhs
Thus , the minimum rate of increase in sales is in the product of Wall clock during the period 2005-2010 .

1. The sales of table clock in 2005 was less than the sales of wall clock in 2005 is nearly by

1. From the given bar diagram , we see
The sales of table clock in 2005 = 9.5 lakhs
The sales of wall clock in 2005 = 30.7 lakhs
Total Change = 30.7 - 9.5 = 21.2 lakhs

 Required percent = Total Change × 100 The sales of wall clock in 2005

##### Correct Option: B

From the given bar diagram , we see
The sales of table clock in 2005 = 9.5 lakhs
The sales of wall clock in 2005 = 30.7 lakhs
Total Change = 30.7 - 9.5 = 21.2 lakhs

 Required percent = Total Change × 100 The sales of wall clock in 2005

 Required percent = 21.2 × 100 = 69.05% 30.7
