    On the basis of given table in question ,
    Production of wheat in 1990 = 560 million tonnes
    Production of wheat in 1991 = 680 million tonnes
    Increase in production = 680 - 560 = 120 million tonnes

    Percentage increase =
    120 × 100
    		 = 21.42%
    560

    Production of rice in 1990 = 240 million tonnes
    Production of rice in 1991 = 300 million tonnes
    Increase in production = 300 - 240 = 60 million tonnes
    Percentage increase =
    60 × 100
    		 = 25%
    240

    Correct Option: C

    On the basis of given table in question ,
    Production of wheat in 1990 = 560 million tonnes
    Production of wheat in 1991 = 680 million tonnes
    Increase in production = 680 - 560 = 120 million tonnes

    Percentage increase =
    120 × 100
    		 = 21.42%
    560

    Production of rice in 1990 = 240 million tonnes
    Production of rice in 1991 = 300 million tonnes
    Increase in production = 300 - 240 = 60 million tonnes
    Percentage increase =
    60 × 100
    		 = 25%
    240

    Production of maize in 1990 = 228 million tonnes
    Production of maize in 1991 = 380 million tonnes
    Increase in production = 380 - 228 = 52 million tonnes
    Percentage increase =
    52 × 100
    		 = 22.80%
    228

    From above it is clear that increase in production for maize is maximum.

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

    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

    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

    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?

    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
