    Total number of students in 1982

    Correct Option: D

    As per given Bar graph we can see that,
    Total passed students in 1982 = 140
    Total number of students in 1982 = 170

    The percentage of students passed in 1982 = Total passed students in 1982x 100
    Total number of students in 1982
    Required percentage =140 x 100
    170

    = 1400 = 826 %

    As per given Bar graph we can see that,
    Total passed students = 140 + 150 + 165 = 455
    Total students = 170 + 195 + 200 = 565

    ∴ Required percentage =Total passed studentsx 100
    Total students

    Correct Option: C

    As per given Bar graph we can see that,
    Total passed students = 140 + 150 + 165 = 455
    Total students = 170 + 195 + 200 = 565

    ∴ Required percentage =Total passed studentsx 100
    Total students

    =455x 100
    565

    = 9110 = 8060 %

    ∵ Required Percentage =Total change in enrollment x 100
    Total number of students in District C in year 2006

    Correct Option: D

    As per given graph, We have
    Number of students in District C in year 2007 = 9
    Number of students in District C in year 2006 = 8
    Total change in enrollment = Students in District C in year 2007 - Students in District Cin year 2006
    Total change in enrollment = 9 - 8 = 1

    ∵ Required Percentage =Total change in enrollment x 100
    Total number of students in District C in year 2006

    = 1 x 100 = 12.5 %
    8

  1. What was the difference between the number of students enrolled in all the 3 districts together in the year 2008 and the number of students enrolled in District B over all the years together?










  1. View Hint View Answer Discuss in Forum

    Required Difference = Students in district B over all the years ( 2005 to 2010 ) − Students in 2008 in all 3 districts

    Correct Option: A

    Students enrolled in 2008 in all three districts ( A + B + C ) = 8000 + 6000 + 7000 = 21000
    Students enrolled in district B over all the years ( 2005 to 2010 ) = 5000 + 4000 + 7000 + 6000 + 4000 + 7000 = 33000
    ∴ Required Difference = Students in district B over all the years ( 2005 to 2010 ) − Students in 2008 in all 3 districts
    ∴ Required Difference = 33000 − 21000 = 12000
