    ∵ Average = sum of total number of products manufactured by the company over all the years
    total number of years

    Correct Option: D

    From above graph ,We have
    sum of total number of products manufactured by the company in given years = (35 + 37.5 + 42.5 + 45 + 47.5 + 52.5) = 260

    ∵ Average = sum of total number of products manufactured by the company in given years
    total number of years

    =260x 103 = 43330 ( Approximate )

    Required % = The number of products sold by the company in the year 2004x 100 %
    The number of products manufactured by the company in the year 2004

    Correct Option: A

    From the given above graph,
    The number of products sold by the company In year 2004 = 25
    The number of products manufactured by the company In year 2004 = 35

    Required % = The number of products sold by the company in the year 2004x 100 %
    The number of products manufactured by the company in the year 2004

    Required % = 25x 100 = 71.43 %
    35


  1. What is the ratio of the number of products not sold by the company in the year 2007 to that not sold in the year 2005?

    Required ratio = Number of products not sold by the company in the year 2007 : Number of products not sold by the company in the year 2005

    Correct Option: C

    As per given graph ,
    Number of products not sold by the company in the year 2007 = Number of products manufactured − Number of products sold = 45 - 42.5 = 2.5 ( in thousands )
    Number of products not sold by the company in the year 2005 = Number of products manufactured − Number of products sold = 37.5 - 30 = 7.5 ( in thousands )
    ∵ ratio = Number of products not sold by the company in the year 2007 : Number of products not sold by the company in the year 2005
    = 2.5 : 7.5 = 1 : 3


  1. What is the difference between the number of products manufactured by the company in the year 2009 and in 2008?











  1. View Hint View Answer Discuss in Forum

    Required Difference = Number of products manufactured in 2009 - Number of products manufactured in 2008

    Correct Option: D

    From the given graph, We can see that,
    Number of products manufactured in 2009 = (52.5) × 1000
    Number of products manufactured in 2008 = (48) × 1000
    Required Difference = Number of products manufactured in 2009 - Number of products manufactured in 2008
    Required Difference = ( 52.5 − 48 ) × 1000 = 4.5 x 1000 = 4500


  1. What is the percent increase in the number of products sold by the company in the year 2006 from the previous year? (Rounded off to two digits after decimal)











  1. View Hint View Answer Discuss in Forum

    Required percent increase = total increase in the number of products sold by the companyx 100 %
    total number of products sold by the company in the year 2005

    Correct Option: B

    From above given graph ,
    Number of products sold by the company in the year 2006 = 40
    Number of products sold by the company in the year 2005 = 30
    Total increase in the number of products sold by the company = Number of products sold by the company in the year 2006 - Number of products sold by the company in the year 2005 = 40 - 30 = 10

    Required percent increase = total increase in the number of products sold by the companyx 100 %
    total number of products sold by the company in the year 2005

    = 10x 100 = 33.33 %
    30
