    According to given bar graph , we have
    Number of students admitted in the year 2002 = 8 thousands
    Total number of students passed out in the years 2003 and 2004 = 9 + 9 = 18 thousands
    Number of given years = 2
    Required ratio = Number of students admitted in the year 2002 : Average of the number of students passed out in the years 2003 and 2004

    Correct Option: B

    As per the given bar graph , we have
    During 2000 to 2003,
    Total students admitted = (6 + 9 + 8 + 12) thousands = 35 thousands
    Total students passed = (4 + 6 + 6 + 9) thousands = 25 thouseands
    ∴ Required ratio = Total students passed : Total students admitted

    Correct Option: D

    As per the given bar graph , we have

    Total students passed = (4 + 6 + 6 + 9) thousands = 25 thouseands
    ∴ Required ratio = Total students passed : Total students admitted
    Required ratio = 25 : 35 = 5 : 7

    According to given bar graph , we have
    Number of students admitted in 2001 = 9000
    Number of students admitted in 2003 = 12000
    Increase = 12000 - 9000 = 3000

    Percentage increase =
    Increase
    		 × 100
    Number of students admitted in 2001


    Correct Option: B
