  1. What is the difference between the number of units manufactured and the number of units sold over the years?








  1. View Hint View Answer Discuss in Forum

    Total number of units manufactured = Units manufactured in 2004 + Units manufactured in 2005 + Units manufactured in 2006 + Units manufactured in 2007 + Units manufactured in 2008
    Total number of units sold = Units sold in 2004 + Units sold in 2005 + Units sold in 2006 + Units sold in 2007 + Units sold in 2008

    Correct Option: C

    Total number of units manufactured = Units manufactured in 2004 + Units manufactured in 2005 + Units manufactured in 2006 + Units manufactured in 2007 + Units manufactured in 2008
    Total number of units manufactured = 4.5 + 5 + 5.5 + 5 + 7 = 27 crores
    Total number of units sold = Units sold in 2004 + Units sold in 2005 + Units sold in 2006 + Units sold in 2007 + Units sold in 2008
    Total number of units sold = 3.5 + 4 + 5 + 3 + 6.5 = 22 crores
    Hence, their difference = 27 crores - 22 crores = 5 crores

  1. What is the respective ratio of the number of units manufactured in the year 2004 to the number of units manufactured in the year 2008?










  1. View Hint View Answer Discuss in Forum

    Required ratio = number of units manufactured in the year 2004 / number of units manufactured in the year 2008

    Correct Option: D

    Required ratio = number of units manufactured in the year 2004 / number of units manufactured in the year 2008
    Required ratio = 4.5 : 7 = 45 : 70 = 9 : 14

  1. What is the average number of units sold over the years?










  1. View Hint View Answer Discuss in Forum

    Average number of units sold = ( Units sold in 2004 + Units sold in 2005 + Units sold in 2006 + Units sold in 2007 + Units sold in 2008 ) / 5

    Correct Option: B

    Average number of units sold = ( Units sold in 2004 + Units sold in 2005 + Units sold in 2006 + Units sold in 2007 + Units sold in 2008 ) / 5
    Average number of units sold = (3.5 + 4 + 5 + 3 + 6.5)/5 = 22/5 = 4.4 crores

  1. What is the approximate percent increase in the number of units sold in the year 2008 from the previous year?








  1. View Hint View Answer Discuss in Forum

    Required percentage of increase = (number of units sold in the year 2008 - number of units sold in the year 2007) x 100 / number of units sold in the year 2007

    Correct Option: D

    Required percentage of increase = (number of units sold in the year 2008 - number of units sold in the year 2007) x 100 / number of units sold in the year 2007
    Required percentage of increase = (6.5 - 3) x 100/3 = 3.5 x 100/3 = 117%

  1. What is respective ratio of the difference between the number of units manufactured and sold in the year 2006 to the difference between the number of units manufactured and sold in the year 2007?

    Required ratio = (number of units manufactured in the year 2006 - number of units sold in the year 2006)/ (number of units manufactured in the year 2007 - number of units sold in the year 2007)

    Correct Option: B

    Required ratio = (number of units manufactured in the year 2006 - number of units sold in the year 2006)/ (number of units manufactured in the year 2007 - number of units sold in the year 2007)
    Required ratio = (5.5 - 5) / (5 - 3) = 0.5 / 2 = 1 / 4 = 1 : 4
