## Introduction to Data Interpretation

#### Data Interpretation

Direction: The bar diagram given below shows the productions (in the unit of thousand pieces) of three types of biscuits by a company in the five consecutive years. Study the diagram and answer the following questions. 1. The ratio of production of glucose biscuits and total production of biscuits in that year was maximum in

1. On the basis of given graph in question ,
Required ratio :

 Year 1993 ⇒ 30 65

 Year 1994 ⇒ 30 75

##### Correct Option: B

On the basis of given graph in question ,
Required ratio :

 Year 1993 ⇒ 30 65

 Year 1994 ⇒ 30 75

 Year 1996 ⇒ 25 75

 Year 1997 ⇒ 22.5 80

1. The production of all the three types of biscuits was maximum in the year

1. According to given bar graph , we have
The production of all the three types of biscuits is maximum in the year 1995

##### Correct Option: A

According to given bar graph , we have
The production of all the three types of biscuits is maximum in the year 1995 .Hence , correct answer is option A .

1. Total production of all the three types of biscuits was the least in the year

1. On the basis of given graph in question ,
Total production of all the three types of biscuits :
In Year 1993 ⇒ 65 thousand (least)
In Year 1994 ⇒ 75 thousand
In Year 1995 ⇒ 85 thousand (maximum)
In Year 1996 ⇒ 75 thousand
In Year 1997 ⇒ 80 thousand

##### Correct Option: A

On the basis of given graph in question ,
Total production of all the three types of biscuits :
In Year 1993 ⇒ 65 thousand (least)
In Year 1994 ⇒ 75 thousand
In Year 1995 ⇒ 85 thousand (maximum)
In Year 1996 ⇒ 75 thousand
In Year 1997 ⇒ 80 thousand
Hence , required answer is 1993 year .

1. The difference (in the unit of thousand pieces) between the total number of cream cracker biscuits manufactured in the years 1993, 1995 and 1997 and the total number of the biscuits of same type in the years 1994 and 1996 is

1. According to given bar graph , we have
Total number of cream cracker biscuits manufactured in the years 1993, 1995 and 1997 = 12.5 + 27.5 + 30 = 70 thousand
Total number of the biscuits of same type in the years 1994 and 1996 = 25 + 20 = 45 thousand
Required difference = Total number of cream cracker biscuits manufactured in the years 1993, 1995 and 1997 : Total number of the biscuits of same type in the years 1994 and 1996

##### Correct Option: B

According to given bar graph , we have
Total number of cream cracker biscuits manufactured in the years 1993, 1995 and 1997 = 12.5 + 27.5 + 30 = 70 thousand
Total number of the biscuits of same type in the years 1994 and 1996 = 25 + 20 = 45 thousand
Required difference = Total number of cream cracker biscuits manufactured in the years 1993, 1995 and 1997 : Total number of the biscuits of same type in the years 1994 and 1996
∴ Required difference = (70 – 45) thousand = 25 thousand

1. The percentage drop in the number of glucose biscuits manufactured from 1994 to 1995 is

1. From the given bar diagram , we see

 Required percentage drop = 30 - 22.5 × 100 30

##### Correct Option: C

From the given bar diagram , we see

 Required percentage drop = 30 - 22.5 × 100 30

 Required percentage drop = 7.5 × 100 = 25% 30
