## Introduction to Data Interpretation

#### Data Interpretation

Direction: Study the following table which shows the number of students appeared and passed in different streams in a University and answer the questions given below it 1. Approximately what percent of students appearing in medical, passed in 2003?

1. On the basis of given table in question ,
Number of students appeared in medical in 2003 = 384
Number of students passed in medical in 2003 = 326

 Required percentage = Number of students passed in medical in 2003 × 100 Number of students appeared in medical in 2003

##### Correct Option: B

On the basis of given table in question ,
Number of students appeared in medical in 2003 = 384
Number of students passed in medical in 2003 = 326

 Required percentage = Number of students passed in medical in 2003 × 100 Number of students appeared in medical in 2003

 Required percentage = 326 × 100 ≈ 85% 384

Direction: Number of toys of five types (A to E) manufactured over the years (in thousands) is given below. Study the table and answer the following questions. 1. The difference of the average number of toys (in thousands) of the type B and C, manufactured over the years, was

1. On the basis of given table in question ,
Difference in production of toys of type B and C :
Year 2002 ⇒ 150 – 78 = 72 thousand
Year 2003 ⇒ 180 – 100 = 80 thousand
Year 2004 ⇒ 175 – 92 = 83 thousand
Year 2005 ⇒ 160 – 120 = 40 thousand
Year 2006 ⇒ 185 – 130 = 55 thousand
Total difference in production of toys of type B and C = 72 + 80 + 83 + 40 + 55 = 330 thousands
Number of types of toys = 5

##### Correct Option: B

On the basis of given table in question ,
Difference in production of toys of type B and C :
Year 2002 ⇒ 150 – 78 = 72 thousand
Year 2003 ⇒ 180 – 100 = 80 thousand
Year 2004 ⇒ 175 – 92 = 83 thousand
Year 2005 ⇒ 160 – 120 = 40 thousand
Year 2006 ⇒ 185 – 130 = 55 thousand
Total difference in production of toys of type B and C = 72 + 80 + 83 + 40 + 55 = 330 thousands
Number of types of toys = 5

 ∴ Required answer = Total difference in production of toys of type B and C Number of types of toys

 Required answer = 330 = 66 thousand 5

1. The approximate percentage increase of the production of all types of toys from 2005 to 2006 was

1. According to given table, we have
Total production of toys in 2005 = 675 thousand
Total production of toys in 2006 = 750 thousand
Increase = 750 - 675 = 75 thousand

 Percentage increase = Increase × 100 = 11% 675

##### Correct Option: C

According to given table, we have
Total production of toys in 2005 = 675 thousand
Total production of toys in 2006 = 750 thousand
Increase = 750 - 675 = 75 thousand

 Percentage increase = Increase × 100 = 11% 675

 Percentage increase = 75 × 100 = 11% 675

1. The percentage drop in production of A type of toys from 2002 to 2004 was

1. As per the given above table , we see
Production of A type of toys in 2002 = 200 thousands
Production of A type of toys in 2004 = 180 thousands
Decrease = 200 - 180 = 20

 Percentage decrease = Decrease × 100 Production of A type of toys in 2002

##### Correct Option: A

As per the given above table , we see
Production of A type of toys in 2002 = 200 thousands
Production of A type of toys in 2004 = 180 thousands
Decrease = 200 - 180 = 20

 Percentage decrease = Decrease × 100 Production of A type of toys in 2002

 Percentage decrease = 20 × 100 = 10% 200

1. The approximate percentage increase in production of D type of toys from 2003 to 2005 was

1. As per the given above table , we see
Production of D type of toys in 2003 = 105 thousands
Production of D type of toys in 2005 = 125 thousands
Increase = 125 - 105 = 20

 Percentage increase = Increase ́ × 100 Production of D type of toys in 2003

##### Correct Option: B

As per the given above table , we see
Production of D type of toys in 2003 = 105 thousands
Production of D type of toys in 2005 = 125 thousands
Increase = 125 - 105 = 20

 Percentage increase = Increase ́ × 100 Production of D type of toys in 2003

 Percentage increase = 20 × 100 ≈ 19% 105
