## Introduction to Data Interpretation

#### Data Interpretation

Direction: The bar graph given below shows the per acre yield (in kg) of different countries. Study the graph carefully and answer the questions. 1. The average yield of the given countries is

1. According to given bar graph , we have
Sum of the per acre yield = 80 + 120 + 132 + 120 + 160 + 200 = 812
Number of countries = 6

 Required average = Sum of the per acre yield Number of countries

 Required average = 80 + 120 + 132 + 120 + 160 + 200 kg. 6

##### Correct Option: D

According to given bar graph , we have
Sum of the per acre yield = 80 + 120 + 132 + 120 + 160 + 200 = 812
Number of countries = 6

 Required average = Sum of the per acre yield Number of countries

 Required average = 80 + 120 + 132 + 120 + 160 + 200 kg. 6

 Required average = 812 = 406 = 135 1 kg. 6 3 3

Direction: Study the following bar graph carefully to answer the questions. 1. The yield per acre produced by Bangladesh is what per cent of the total yield per acre produced by all countries?

1. On the basis of given graph in question ,
Total product per acre = 490 + 322 = 812 quintal
The yield per acre produced by Bangladesh = 120

 ∴ Required percent = The yield per acre produced by Bangladesh × 100 Total product per acre

##### Correct Option: C

On the basis of given graph in question ,
Total product per acre = 490 + 322 = 812 quintal
The yield per acre produced by Bangladesh = 120

 ∴ Required percent = The yield per acre produced by Bangladesh × 100 Total product per acre

 Required percent = 120 × 100 ≈ 14.8% 812

1. If the yield per acre is arranged in ascending order, then what is the difference between the yield per acre of first three countries and last three countries?

1. From the given bar diagram , we see
Ascending order of yield per acre : 82, 120, 120, 130, 160, 200
The yield per acre of first three countries = 130 + 160 + 200 = 490
The yield per acre of last three countries = 82 + 120 + 120 = 322
∴ Required difference = The yield per acre of first three countries – The yield per acre of last three countries

##### Correct Option: A

From the given bar diagram , we see
Ascending order of yield per acre : 82, 120, 120, 130, 160, 200
The yield per acre of first three countries = 130 + 160 + 200 = 490
The yield per acre of last three countries = 82 + 120 + 120 = 322
∴ Required difference = The yield per acre of first three countries – The yield per acre of last three countries
Required difference = (490 – 322) quintals = 168 quintals

1. The yield per acre of India is what percent more than that of Pakistan?

1. According to given bar graph , we have
The yield per acre of India = 200
The yield per acre of Pakistan = 160
Total Change = 200 - 160 = 40

 Required percent = Total Change × 100 The yield per acre of Pakistan

##### Correct Option: A

According to given bar graph , we have
The yield per acre of India = 200
The yield per acre of Pakistan = 160
Total Change = 200 - 160 = 40

 Required percent = Total Change × 100 The yield per acre of Pakistan

 Required percent = 40 × 100 = 25% 160

Direction: The sub- divided bar diagram given below depicts the result of B.Com. students of a college for 3 years. Study the graph and answer the given questions. 1. In which year, did the college have the best result for B. Com?

1. From the given bar diagram , we see
Total students in year 2006 = 170
Students who passed in year 2006 = 140

 Pass percentage :Year 2006 ⇒ 140 × 100 ≈ 82.35 ; 170

Total students in year 2007 = 190
Students who passed in year 2007 = 150
 Pass percentage : Year 2007 ⇒ 150 × 100 ≈ 78.94 ; 190

##### Correct Option: C

From the given bar diagram , we see
Total students in year 2006 = 170
Students who passed in year 2006 = 140

 Pass percentage :Year 2006 ⇒ 140 × 100 ≈ 82.35 ; 170

Total students in year 2007 = 190
Students who passed in year 2007 = 150
 Pass percentage : Year 2007 ⇒ 150 × 100 ≈ 78.94 ; 190

Total students in year 2008 = 240
Students who passed in year 2008 = 180
 Pass percentage : Year 2008 ⇒ 180 × 100 = 75% 240

Hence , correct answer is 2007 year .
