    Percentage production =Total production of company C in 1993 and 1994 X 100
    Total production of company A in 1991 and 1992

    Correct Option: E

    Percentage production = Total production of company C in 1993 and 1994 X 100
    Total production of company A in 1991 and 1992

    Percentage production =60 + 60 X 100
    50 + 40

    Percentage production =120 X 100 = 133.3 %
    90


Direction: Study the following graphs carefully to answer these questions.

  1. What is the ratio of total production for two years together for unit B to that for C?











  1. View Hint View Answer Discuss in Forum

    Total production by unit B in 2001 and 2002 together = (75 + 60) = 135 Million tons
    Total production by unit C in 2001 and 2002 together = (100 + 110) = 210 Million tons

    Correct Option: A

    Total production by unit B in 2001 and 2002 together = (75 + 60) = 135 Million tons
    Total production by unit C in 2001 and 2002 together = (100 + 110) = 210 Million tons
    ∴ Required ratio = (135:210) = 9:14.



  1. What is the average production of all the units (in million tons) for the year 2002?











  1. View Hint View Answer Discuss in Forum

    average production for the year 2002 = production of ( unit A + unit B + unit C + unit D + unit E + unit F ) in 2002
    Total number of units

    Correct Option: D

    average production for the year 2002 = production of ( unit A + unit B + unit C + unit D + unit E + unit F ) in 2002
    Total number of units


    average production of all the units (in million tons) for the year 2002 =10 + 15 + 25 + 15 + 30 + 25
    6


    = 95 Million tons


  1. What is the total production of units C, D and E together for both the years? (in Million tons)











  1. View Hint View Answer Discuss in Forum

    As we can see in the graph that
    Total production by unit C, D and E in year 2001 and 2002 together = (100 + 110 + 95 + 100 + 85 + 105 )

    Correct Option: B

    As we can see in the graph that
    Total production by unit C, D and E in year 2001 and 2002 together = (100 + 110 + 95 + 100 + 85 + 105 )
    Required total production = (100 + 110 + 95 + 100 + 85 + 105) = 595 Million tons.



  1. Average production of three units A, B and C in 2001 is what % of the average production of units D, E and F in 2002? (rounded off to two digits after decimal)











  1. View Hint View Answer Discuss in Forum

    Average production of unit A, B and C in 2001 = production of ( unit A + unit B + unit C ) in 2001
    Number of units (A + B + C )

    Average production of unit D, E and F in 2002 = Production of ( unit D + unit E + unit F ) in 2002
    Number of units (D + E + F )

    Correct Option: C

    Average production of unit A, B and C in 2001 = production of ( unit A + unit B + unit C ) in 2001
    Number of units (A + B + C )

    Put the value of Unit A , B and C from given graph , we will get
    Average production of unit A, B and C in 2001 = 90 + 75 + 100
    3

    Average production of unit A, B and C in 2001 = 265
    3

    Similarly
    Average production of unit D, E and F in 2002 = Production of ( unit D + unit E + unit F ) in 2002
    Number of units (D + E + F )

    Put the value of Unit D , E and F from given graph , we will get
    Average production of unit D, E and F in 2002 = ( 100 + 105 + 85 )
    3

    Average production of unit D, E and F in 2002 = 290
    3

    ∴ Required % = Average production of unit A, B and C in 2001 x 100
    Average production of unit D, E and F in 2002


    ∴ Required % = 265 x 3x 100= 91.38
    3 x 290
