    As per the given bar graph , we have
    Total enrollments at State University in the year 2000 = 12000
    Tuition fee per enrolment = Rs. 6500
    Required total collected amount as fees = Total enrollments at State University × Tuition fee per enrolment

    Correct Option: B

    As per the given bar graph , we have
    Total enrollments at State University in the year 2000 = 12000
    Tuition fee per enrolment = Rs. 6500
    Required total collected amount as fees = Total enrollments at State University × Tuition fee per enrolment
    Required total collected amount as fees = Rs. (12000 × 6500) = Rs. 78000000

    On the basis of given graph in question ,
    Total enrollments in the year 1980 and 2000 at the State University = 8000 + 12000 = 20000
    Total enrollments in the year 1980 and 2000 at the Central University = 10000 + 14000 = 24000

    Correct Option: D

    On the basis of given graph in question ,
    Total enrollments in the year 1980 and 2000 at the State University = 8000 + 12000 = 20000
    Total enrollments in the year 1980 and 2000 at the Central University = 10000 + 14000 = 24000
    Required ratio = 20000 : 24000
    Hence , Required ratio = 20 : 24 = 5 : 6

    According to given bar diagram , we see
    Number of students were enrolled at State and Central University in 1980 = 8000 + 10000 = 18000
    Number of students were enrolled at State and Central University in 1990 = 14000 + 12000 = 26000
    Number of students were enrolled at State and Central University in 2000 = 12000 + 14000 = 26000

    Correct Option: C

    According to given bar diagram , we see
    Number of students were enrolled at State and Central University in 1980 = 8000 + 10000 = 18000
    Number of students were enrolled at State and Central University in 1990 = 14000 + 12000 = 26000
    Number of students were enrolled at State and Central University in 2000 = 12000 + 14000 = 26000
    Required total enrollment = (18000 + 26000 + 26000) = 70000

    From the given bar diagram , we see
    Number of students were enrolled at State University in 1990 = 14000
    Number of students were enrolled at Central University in 1990 = 12000
    Required answer = Number of students were enrolled at State University in 1990 - Number of students were enrolled at Central University in 1990

    Correct Option: C

    From the given bar diagram , we see
    Number of students were enrolled at State University in 1990 = 14000
    Number of students were enrolled at Central University in 1990 = 12000
    Required answer = Number of students were enrolled at State University in 1990 - Number of students were enrolled at Central University in 1990
    Required answer = 14000 – 12000 = 2000

    Total number of the road accidents by cars in the year 2008, 2011 and 2013 = 40 + 20+ 20 = 80
    Number of given years = 3

    Required ratio =
    Total number of the road accidents by buses
    		 :
    Total number of the road accidents by cars
    33

    Required ratio = 100 : 80 = 5 : 4
