## Introduction to Data Interpretation

#### Data Interpretation

Direction: Study the table carefully and answer the questions given below. 1. In which year, the production of scooters of all factories was equal to the yearly average number of scooters produced during 1985- 89?

1. As per the given above table , we can see
Total production of scooters of all factories = 115 + 108 + 149 + 102 + 101 = 575
Number of given years = 5

 Required Average = Total production of scooters of all factories Number of given years

##### Correct Option: A

As per the given above table , we can see
Total production of scooters of all factories = 115 + 108 + 149 + 102 + 101 = 575
Number of given years = 5

 Required Average = Total production of scooters of all factories Number of given years

 Required Average = 575 = 115 5

Clearly, it was in the year 1985.

Direction: Following table gives the population of a locality from 1988 to 1992. Read the table and answer the questions. 1. Increase or decrease of population in 1992 over 1991 is :

1. On the basis of given table in question ,
Total population in 1992 = 160998
Total population in 1991 = 153922 – 5337 = 148585
∴ Increase in population in 1992 over 1991 = Total population in 1992 - Total population in 1991

##### Correct Option: B

On the basis of given table in question ,
Total population in 1992 = 160998
Total population in 1991 = 153922 – 5337 = 148585
∴ Increase in population in 1992 over 1991 = Total population in 1992 - Total population in 1991
Increase in population in 1992 over 1991 = 160998 – 148585 = 12413

1. Number of women in 1991 is :

1. On the basis of given table in question ,
Total population in 1990 = 153922
Decrease in 1991 = 5337
Total population in 1991 = Total population in 1990 - Decrease in 1991 = 153922 – 5337 = 148585
Total population of men and children in 1991 = 69395 + 21560 = 90955
Number of women in 1991 = Total population in 1991 – total population of men and children in 1991

##### Correct Option: A

On the basis of given table in question ,
Total population in 1990 = 153922
Decrease in 1991 = 5337
Total population in 1991 = Total population in 1990 - Decrease in 1991 = 153922 – 5337 = 148585
Total population of men and children in 1991 = 69395 + 21560 = 90955
Number of women in 1991 = Total population in 1991 – total population of men and children in 1991 = 148585 – 90955 = 57630

1. Number of children in 1989 is :

1. According to given table, we have
Total population in 1989 = 158577
Total population of men and women = 70391 + 62516 = 132907
Number of children in 1989 = Total population in 1989 – Total population of men and women

##### Correct Option: A

According to given table, we have
Total population in 1989 = 158577
Total population of men and women = 70391 + 62516 = 132907
Number of children in 1989 = Total population in 1989 – Total population of men and women = 158577 – 132907 = 25670

1. The total population in 1989 is :

1. On the basis of given table in question ,
Population in 1988 = 146947
Increase in 1989 = 11630
The total population in 1989 = Population in 1988 + Increase in 1989

##### Correct Option: B

On the basis of given table in question ,
Population in 1988 = 146947
Increase in 1989 = 11630
The total population in 1989 = Population in 1988 + Increase in 1989 = 146947 + 11630 = 158577
