## Introduction to Data Interpretation

#### Data Interpretation

Direction: The following table shows the production of food grains (in million tonnes) in a State for the period 1988 to 1992. Read the table and answer the following questions.

1. During 1990, the percentage of decrease in production of maize as against the previous year was:

1. As per the given above table , we see
Production of maize in 1990 = 228 million tonnes
Production of maize in 1989 = 234 million tonnes
Decrease in production = 234 - 228 = 6 million tonnes

 Percentage decrease = Decrease in production × 100 Production of maize in 1989

##### Correct Option: B

As per the given above table , we see
Production of maize in 1990 = 228 million tonnes
Production of maize in 1989 = 234 million tonnes
Decrease in production = 234 - 228 = 6 million tonnes

 Percentage decrease = Decrease in production × 100 Production of maize in 1989

 Percentage decrease = 6 × 100 = 2.56% 234

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. The number of students passing in all streams was maximum in the year.

1. According to given table, we have
Total number of students passing in all streams :
Year 2001 ⇒ 289 + 246 + 69 + 1310 = 1914
Year 2002 ⇒ 312 + 364 + 62 + 1129 = 1867
Year 2003 ⇒ 212 + 326 + 102 + 1176 = 1816
Year 2004 ⇒ 246 + 298 + 92 + 1074 = 1710
Year 2005 ⇒ 382 + 382 + 74 + 1326 = 2164 (maximum)

##### Correct Option: B

According to given table, we have
Total number of students passing in all streams :
Year 2001 ⇒ 289 + 246 + 69 + 1310 = 1914
Year 2002 ⇒ 312 + 364 + 62 + 1129 = 1867
Year 2003 ⇒ 212 + 326 + 102 + 1176 = 1816
Year 2004 ⇒ 246 + 298 + 92 + 1074 = 1710
Year 2005 ⇒ 382 + 382 + 74 + 1326 = 2164 (maximum)
Year 2006 ⇒ 286 + 405 + 63 + 1207 = 1961
Hence , option B is correct answer .

1. The number of students appearing in all streams was minimum in the year

1. According to given table, we have
Total number of students appearing in all streams in year 2002 ⇒ 2136
Total number of students appearing in all streams in year 2003 ⇒ 2179
Total number of students appearing in all streams in year 2004 ⇒ 1991 (minimum)
Total number of students appearing in all streams in year 2006 ⇒ 2298

##### Correct Option: C

According to given table, we have
Total number of students appearing in all streams in year 2002 ⇒ 2136
Total number of students appearing in all streams in year 2003 ⇒ 2179
Total number of students appearing in all streams in year 2004 ⇒ 1991 (minimum)
Total number of students appearing in all streams in year 2006 ⇒ 2298
Hence , required answer is 2004 year.

1. Approximately what percent of total students appearing in 2004, appeared in commerce stream?

1. As per the given above table , we see
Total number of students appearing in 2004 = 310 + 395 + 106 + 1180 = 1991
Number of students appearing in commerce in 2004 = 1180

 Required percentage = Number of students appearing in commerce in 2004 × 100 Total number of students appearing in 2004

##### Correct Option: D

As per the given above table , we see
Total number of students appearing in 2004 = 310 + 395 + 106 + 1180 = 1991
Number of students appearing in commerce in 2004 = 1180

 Required percentage = Number of students appearing in commerce in 2004 × 100 Total number of students appearing in 2004

 Required percentage = 1180 × 100 ≈ 59.3% 1991

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
