Direction: Study the following Bar graph and answer the questions. The Bar Graph gives the annual rates of inflation in percentages for 1975 and 1987.

  1. The change in rate of inflation was least in which of the following?

    From the given bar diagram , we see
    Inflation rate of world in 1987 = 16
    Inflation rate of world in 1975 = 14.6
    Change in world = Inflation rate of world in 1987 – Inflation rate of world in 1975

    Correct Option: C

    From the given bar diagram , we see
    Inflation rate of world in 1987 = 16
    Inflation rate of world in 1975 = 14.6
    Change in world = Inflation rate of world in 1987 – Inflation rate of world in 1975
    Change in world = 16 – 14.6 = 1.4

  1. From 1975 to 1987, inflation rate increased in the third world countries approximately by

    On the basis of given graph in question ,
    Inflation rate of the third world in 1987 = 36.2
    Inflation rate of the third world in 1975 = 26.6
    Increase in rate = 36.2 - 26.6 = 9.6

    Required percentage increase = Increase in rate × 100
    Inflation rate of the third world in 1975

    Correct Option: D

    On the basis of given graph in question ,
    Inflation rate of the third world in 1987 = 36.2
    Inflation rate of the third world in 1975 = 26.6
    Increase in rate = 36.2 - 26.6 = 9.6

    Required percentage increase = Increase in rate × 100
    Inflation rate of the third world in 1975

    Required percentage increase =
    9.6 × 100
    		≈ 36%
    26.6

Direction: Study the bar diagram and answer the following questions.

  1. The ratio of the average of the marks obtained in Biology for two terms to the average of the marks obtained in English and Mathematics for first term only is

    According to given bar graph , we have
    Total marks obtained in Biology for two terms = 85 + 60 = 145
    Total marks obtained in English and Mathematics for first term = 70 + 100 = 170
    Required ratio = average of the marks obtained in Biology for two terms : average of the marks obtained in English and Mathematics for first term

    Correct Option: C

    According to given bar graph , we have
    Total marks obtained in Biology for two terms = 85 + 60 = 145
    Total marks obtained in English and Mathematics for first term = 70 + 100 = 170
    Required ratio = average of the marks obtained in Biology for two terms : average of the marks obtained in English and Mathematics for first term

    Required ratio =
    85 + 60
    		=
    70 + 100
    		= 145 : 170 = 29 : 34
    22

  1. What is the percentage of marks obtained in Chemistry for both the terms?








  1. View Hint View Answer Discuss in Forum

    From the given bar diagram , we see
    Total marks obtained in Chemistry for both the terms = 70 + 65 = 135

    Required percent = Total marks obtained in Chemistry for both the terms × 100
    200

    Correct Option: D

    From the given bar diagram , we see
    Total marks obtained in Chemistry for both the terms = 70 + 65 = 135

    Required percent = Total marks obtained in Chemistry for both the terms × 100
    200

    Required percent =
    135
    		 = 67.5
    2

  1. Difference of marks obtained in both the terms by the students is maximum in








  1. View Hint View Answer Discuss in Forum

    According to given bar graph , we have
    Difference between the marks in Biology = 85 – 60 = 25
    Difference between the marks in Maths = 100 – 80 = 20
    Difference between the marks in Physics = 90 – 75 = 15

    Correct Option: C

    According to given bar graph , we have
    Difference between the marks in Biology = 85 – 60 = 25
    Difference between the marks in Maths = 100 – 80 = 20
    Difference between the marks in Physics = 90 – 75 = 15
    Hence , required answer is Biology .
