## Introduction to Data Interpretation

#### Data Interpretation

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

1. The number of children in 1988 is :

1. According to given table, we have
Total population in 1988 = 146947
Total number of men and women in 1988 = 65104 + 60387 = 125491
The number of children in 1988 = Total population in 1988 - Total number of men and women in 1988

##### Correct Option: D

According to given table, we have
Total population in 1988 = 146947
Total number of men and women in 1988 = 65104 + 60387 = 125491
The number of children in 1988 = Total population in 1988 - Total number of men and women in 1988
The number of children in 1988 = 146947 – 125491 = 21456
