## Introduction to Data Interpretation

#### Data Interpretation

Direction: The graph shows the production of food grains of a country in different yea\$ Study the graph and answer the questions.

1. The percentage increase in production from 1984 to 1985 was

1. On the basis of given graph in question ,
The production of food grains in the year 1984 = 15 thousand tonnes
The production of food grains in the year 1985 = 30 thousand tonnes
Increase = 30 - 15 = 15 thousand tonnes

 Percentage increase = Increase × 100 The production of food grains in the year 1984

##### Correct Option: D

On the basis of given graph in question ,
The production of food grains in the year 1984 = 15 thousand tonnes
The production of food grains in the year 1985 = 30 thousand tonnes
Increase = 30 - 15 = 15 thousand tonnes

 Percentage increase = Increase × 100 The production of food grains in the year 1984

 Percentage increase = 15 × 100 = 100% 15

1. The difference between the production of food grains in the years 1981 and 1985 is

1. As per the given bar graph , we have
The production of food grains in the year 1981 = 35 thousand tonnes
And the production of food grains in the year 1985 = 30 thousand tonnes
Required difference = The production of food grains in the year 1981 - The production of food grains in the year 1985

##### Correct Option: C

As per the given bar graph , we have
The production of food grains in the year 1981 = 35 thousand tonnes
And the production of food grains in the year 1985 = 30 thousand tonnes
Required difference = The production of food grains in the year 1981 - The production of food grains in the year 1985 = 35 - 30 = 5 thousand tonnes
Required difference = 5000 tonnes

1. The sum of the production of food grains in the years 1982 and 1984 is equal to that in the year :

1. According to given bar graph , we have
The production of food grains in the year 1982 = 20 thousand tonnes
And the production of food grains in the year 1984 = 15 thousand tonnes
Total foodgrain production in 1982 and 1984 = (20 + 15) thousand tonnes = 35 thousand tonnes = Production in 1981

##### Correct Option: B

According to given bar graph , we have
The production of food grains in the year 1982 = 20 thousand tonnes
And the production of food grains in the year 1984 = 15 thousand tonnes
Total foodgrain production in 1982 and 1984 = (20 + 15) thousand tonnes = 35 thousand tonnes = Production in 1981
Hence , required answer is 1981 .

Direction: Study the Bar diagram carefully and answer the questions.
The Bar diagram shows the trends of foreign direct investment (FDI) into India from all over the World (in Rs. crores).

1. The absolute difference in FDI to India between 1996 and 1997 is

1. As per the given bar graph ,
FDI in 1997 = 31.36 billion
and FDI in 1996 = 24.23 billion
Required difference = FDI in 1997 - FDI in 1996

##### Correct Option: B

As per the given bar graph ,
FDI in 1997 = 31.36 billion
and FDI in 1996 = 24.23 billion
Required difference = FDI in 1997 - FDI in 1996
Required difference = \$ (31.36 – 24.23) billion = \$ 7.13 billion

1. The ratio of investment in 1997 to the average investment is

1. On the basis of given graph in question ,
Sum of investment in 1992 - 1992 = 5.7 + 10.15 + 20.16 + 10.22 + 24.23 + 31.36
Number of given years = 6

 Average investment = 5.7 + 10.15 + 20.16 + 10.22 + 24.23 + 31.36 billion 6

##### Correct Option: A

On the basis of given graph in question ,
Sum of investment in 1992 - 1992 = 5.7 + 10.15 + 20.16 + 10.22 + 24.23 + 31.36
Number of given years = 6

 Average investment = 5.7 + 10.15 + 20.16 + 10.22 + 24.23 + 31.36 billion 6

 Average investment = 101.82 = 16.97 billion 6

∴ Required ratio = 31.36 : 16.97
∴ Required ratio ≈ 2 : 1
