    As per the given bar graph in question ,
    Number of the students who use Car = 6 units
    Number of the students who use Rickshaw = 16 units
    Required ratio = Number of the students who use Car : Number of the students who use Rickshaw

    Correct Option: D

    As per the given bar graph in question ,
    Number of the students who use Car = 6 units
    Number of the students who use Rickshaw = 16 units
    Required ratio = Number of the students who use Car : Number of the students who use Rickshaw
    Required ratio = 6 : 16 = 3 : 8

    		× 100
    660

    Correct Option: C

    On the basis of given graph in question ,
    Number of students who use bus = 150

    ∴ Required percentage =
    150
    		× 100
    660

    Required percentage =
    250
    		= 22

    On the basis of given graph in question ,
    Total number of students = (6 + 15 + 11 + 18 + 16) × 10 = 66 × 10 = 660

    Correct Option: D

    On the basis of given graph in question ,
    Total number of students = (6 + 15 + 11 + 18 + 16) × 10 = 66 × 10 = 660

Direction: Sales of books (in thousands} from six branches (B1, B2, B3, B4, B5, B6) of a publishing company are given below. Study the graph and answer the following questions.

    As per the given bar graph in question , we have
    B1 + B4 = B2 + B6 = B3 + B5 = 100000
    B3 – B5 = 55 – 45 = 10 thousand
    B4 – B1 = 80 – 20 = 60 thousand
    B6 – B2 = 60 – 40 = 20 thousand

    Correct Option: B

    As per the given bar graph in question , we have
    B1 + B4 = B2 + B6 = B3 + B5 = 100000
    B3 – B5 = 55 – 45 = 10 thousand
    B4 – B1 = 80 – 20 = 60 thousand
    B6 – B2 = 60 – 40 = 20 thousand
    ∴ Minimum difference = 10
