    As per the given bar graph , we have
    Number of commerce students from 1990–91 to 1992–93 = 200 + 250 + 250 = 700
    Number of law students from 1990–91 to 1992–93 = 150 + 200 + 250 = 600
    Required ratio = Number of commerce students from 1990–91 to 1992–93 : Number of law students from 1990–91 to 1992–93

    Correct Option: B

    As per the given bar graph , we have
    Number of commerce students from 1990–91 to 1992–93 = 200 + 250 + 250 = 700
    Number of law students from 1990–91 to 1992–93 = 150 + 200 + 250 = 600
    Required ratio = Number of commerce students from 1990–91 to 1992–93 : Number of law students from 1990–91 to 1992–93
