## Introduction to Data Interpretation

#### Data Interpretation

Direction: Study the bar diagram carefully and answer the following questions. 1. The export to Hongkong is approximately how many times the exports to Germany?

1. According to given bar graph , we have
The export to Hongkong = 10.6
The export to Germany = 1.2

 ∴ Required answer = The export to Hongkong The export to Germany

##### Correct Option: C

According to given bar graph , we have
The export to Hongkong = 10.6
The export to Germany = 1.2

 ∴ Required answer = The export to Hongkong The export to Germany

 ∴ Required answer = 10.6 ≈ 10 1.2

1. The ratio of the total exports to Japan, Belgium and Hongkong to the export to rest of the countries in 1991–92 is nearly :

1. From the given bar diagram , we see
Total exports to Japan, Belgium and Hongkong = 12.5 + 12.1 + 10.6 = 35.2
Total exports = \$ (22.6 + 12.5 + 12.1 + 10.6 + 3.3 + 2.5 + 1.6 × 3 + 1.2) billion = \$ 69.6 billion
Total exports of remaining countries = 69.6 - 35.2 = 34.4
Required ratio = Total exports to Japan, Belgium and Hongkong : Total exports of remaining countries

##### Correct Option: A

From the given bar diagram , we see
Total exports to Japan, Belgium and Hongkong = 12.5 + 12.1 + 10.6 = 35.2
Total exports = \$ (22.6 + 12.5 + 12.1 + 10.6 + 3.3 + 2.5 + 1.6 × 3 + 1.2) billion = \$ 69.6 billion
Total exports of remaining countries = 69.6 - 35.2 = 34.4
Required ratio = Total exports to Japan, Belgium and Hongkong : Total exports of remaining countries
∴ Required ratio = 35.2 : 34.4 ≈ 35 : 34

1. The country to which twice the export is nearly equal to the average exports in 1991–92 is

1. According to given bar graph , we have
Total exports = \$ (22.6 + 12.5 + 12.1 + 10.6 + 3.3 + 2.5 + 1.6 × 3 + 1.2) billion = \$ 69.6 billion
Number of countries = 10

 ∴ Average exports = Total exports Number of countries

table>∴ Average exports =
69.6
= \$ 6.96 billion 10

##### Correct Option: D

According to given bar graph , we have
Total exports = \$ (22.6 + 12.5 + 12.1 + 10.6 + 3.3 + 2.5 + 1.6 × 3 + 1.2) billion = \$ 69.6 billion
Number of countries = 10

 ∴ Average exports = Total exports Number of countries

table>∴ Average exports =
69.6
= \$ 6.96 billion 10
Exports to UAE = \$ 3.3 billion
Hence , required answer is UAE .

1. The ratio of the sum of the exports to the bottom six countries to the total exports to all the given countries in 1991 – 1992 is approximately :

1. On the basis of given graph in question ,
Total exports = \$ (22.6 + 12.5 + 12.1 + 10.6 + 3.3 + 2.5 + 1.6 × 3 + 1.2) billion = \$ 69.6 billion
Total exports to bottom six countries = \$ (3.3 + 2.5 + 1.6 × 3 + 1.2) billion = \$ 11.8 billion

 Required Ratio = Total exports to bottom six countries Total exports

##### Correct Option: A

On the basis of given graph in question ,
Total exports = \$ (22.6 + 12.5 + 12.1 + 10.6 + 3.3 + 2.5 + 1.6 × 3 + 1.2) billion = \$ 69.6 billion
Total exports to bottom six countries = \$ (3.3 + 2.5 + 1.6 × 3 + 1.2) billion = \$ 11.8 billion

 Required Ratio = Total exports to bottom six countries Total exports

 ∴ Required Ratio = 11.8 ≈ 1 69.6 6

Direction: Study the following bar–diagram carefully and answer the questions. 1. The ratio of the number of years, in which the foreign exchange reserves are above the average reserves, to those in which reserves are below the average reserves, is

1. From the given bar diagram , we see
Total foreign exchange reserves = 2640 + 3720 + 2520 + 3360 + 3120 + 4320 + 5040 + 3120
Total number of years = 8

 Average foreign exchange reserves = (2640 + 3720 + 2520 + 3360 + 3120 + 4320 + 5040 + 3120) million dollar 8

 Average foreign exchange reserves = 27840 million dollar 8

##### Correct Option: C

From the given bar diagram , we see
Total foreign exchange reserves = 2640 + 3720 + 2520 + 3360 + 3120 + 4320 + 5040 + 3120
Total number of years = 8

 Average foreign exchange reserves = (2640 + 3720 + 2520 + 3360 + 3120 + 4320 + 5040 + 3120) million dollar 8

 Average foreign exchange reserves = 27840 million dollar 8

Average foreign exchange reserves = 3480 million dollar
Years that have more than average foreign exchange reserves ⇒ 2007, 2011, 2012
Number of the foreign exchange reserves above the average = 3
Number of the foreign exchange reserves below the average = 5
Required ratio = 3 : 5
