  1. What was the difference between the average amount invested in raw materials during the given period and the average value of sales of finished goods during this period?








  1. View Hint View Answer Discuss in Forum

    From the given bar diagram , we see
    Total amount invested in raw materials in given years = 120 + 225 + 375 + 330 + 252 + 420 = 1995
    Number of given years = 6

    Average of total investment =
    Total amount invested in raw materials in given years
    Number of given years

    Average of total investment =
    1995
    		 = $ 332.5 lakhs
    6

    Total value of sales of finished goods in given years = 200 + 300 + 500 + 400 + 600 + 460 = 2460
    Number of given years = 6
    Average value of sales =
    Total value of sales of finished goods in given years
    Number of given years

    Correct Option: D

    From the given bar diagram , we see
    Total amount invested in raw materials in given years = 120 + 225 + 375 + 330 + 252 + 420 = 1995
    Number of given years = 6

    Average of total investment =
    Total amount invested in raw materials in given years
    Number of given years

    Average of total investment =
    1995
    		 = $ 332.5 lakhs
    6

    Total value of sales of finished goods in given years = 200 + 300 + 500 + 400 + 600 + 460 = 2460
    Number of given years = 6
    Average value of sales =
    Total value of sales of finished goods in given years
    Number of given years

    Average value of sales =
    2460
    		 = $ 410 lakhs
    6

    Difference = Average value of sales - Average of total investment
    Difference = 410 – 332.5 = 77.5 lakh

  1. In which year, there has been a maximum percentage increase in the amount invested in raw materials as compared to the previous year?

    According to given bar graph , we have
    The amount invested in raw materials in 1996 = $ 225 lakhs
    The amount invested in raw materials in 1995 = $ 120 lakhs
    Increase = 225 - 120 = $ 105 lakhs
    In Year 1996 ⇒

    Percentage increase =
    Increase
    The amount invested in raw materials in 1995

    Percentage increase = 105 × 100 ≈ 87.5%
    120

    The amount invested in raw materials in 1996 = $ 225 lakhs
    The amount invested in raw materials in 1997 = $ 375 lakhs
    Increase = 375 - 225 = $ 150 lakhs

    Correct Option: A

    According to given bar graph , we have
    The amount invested in raw materials in 1996 = $ 225 lakhs
    The amount invested in raw materials in 1995 = $ 120 lakhs
    Increase = 225 - 120 = $ 105 lakhs
    In Year 1996 ⇒

    Percentage increase =
    Increase
    The amount invested in raw materials in 1995

    Percentage increase = 105 × 100 ≈ 87.5%
    120

    The amount invested in raw materials in 1996 = $ 225 lakhs
    The amount invested in raw materials in 1997 = $ 375 lakhs
    Increase = 375 - 225 = $ 150 lakhs
    In Year 1997 ⇒
    Percentage increase = 150 × 100 ≈ 67%
    225

    Therefore , required answer is 1996 year.

    On the basis of given graph in question ,
    Total Kharif production of the given years = 5 + 4 + 4 + 3 + 4 = 20
    Number of give years = 5

    Required average =
    Total Kharif production of the given years
    Number of give years

    Correct Option: A

    On the basis of given graph in question ,
    Total Kharif production of the given years = 5 + 4 + 4 + 3 + 4 = 20
    Number of give years = 5

    Required average =
    Total Kharif production of the given years
    Number of give years

    Required average = 5 + 4 + 4 + 3 + 4million tonnes = 4 million tonnes
    5

Direction: Study the following multiple bar graph carefully and answer the questions

  1. In which year or years, the difference between the number of working and non-working women the lowest?








  1. View Hint View Answer Discuss in Forum

    From the given bar diagram , we see
    The number of non-working women in the year 2006 = 60 millions
    The number of working women in the year 2006 = 50 millions
    Difference in 2006 = 60 - 50 = 10 millions
    The number of non-working women in the year 2007 = 50 millions
    The number of working women in the year 2007 = 60 millions
    Difference in 2007 = 60 - 50 = 10 millions

    Correct Option: A

    From the given bar diagram , we see
    The number of non-working women in the year 2006 = 60 millions
    The number of working women in the year 2006 = 50 millions
    Difference in 2006 = 60 - 50 = 10 millions
    The number of non-working women in the year 2007 = 50 millions
    The number of working women in the year 2007 = 60 millions
    Difference in 2007 = 60 - 50 = 10 millions
    Hence , required years are 2006 and 2007 in which difference between them is lowest .

  1. In which year was the difference between the number of working and non-working women the highest?








  1. View Hint View Answer Discuss in Forum

    On the basis of given graph in question ,
    The number of non-working women in the year 2010 = 35 millions
    The number of working women in the year 2010 = 85 millions
    Required difference = The number of working women in the year 2010 - The number of non-working women in the year 2010

    Correct Option: D

    On the basis of given graph in question ,
    The number of non-working women in the year 2010 = 35 millions
    The number of working women in the year 2010 = 85 millions
    Required difference = The number of working women in the year 2010 - The number of non-working women in the year 2010
    Difference in 2010 = 85 – 35 = 50 million
