    According to given bar graph , we have
    Number of students passed in 2nd and 1st division in 2008 = 80
    Total number of students passed in 2008 = 140
    ∴ Students passed in third division in 2008 = Total number of students passed in 2008 - Number of students passed in 2nd and 1st division in 2008

    Correct Option: B

    According to given bar graph , we have
    Number of students passed in 2nd and 1st division in 2008 = 80
    Total number of students passed in 2008 = 140
    ∴ Students passed in third division in 2008 = Total number of students passed in 2008 - Number of students passed in 2nd and 1st division in 2008
    Students passed in third division in 2008 = 140 – 80 = 60
