  1. Approximately what was the expenditure in 1994?










  1. View Hint View Answer Discuss in Forum

    Let us assume E was the expenditure in 1994.
    As we can see in the graph given that,
    Profit = 15 % ,
    Income in 1994 = 160
    Then according to question,
    E + E x 15 % = 160

    Correct Option: C

    Let us assume E was the expenditure in 1994.
    As we can see in the graph given that,
    Profit = 15 % ,
    Income in 1994 = 160
    Then according to question,
    E + E x 15 % = 160
    E + E x 15 /100 = 160
    (100E + E x 15 ) /100 = 160
    115E / 100 = 160
    115E = 160 x 100
    E = 160 x 100 / 115
    E = 139.13
    Expenditure in 1994 E = 139.13 ≈ 140 Million

Direction: Study the following graph carefully to answer the questions given below it.

  1. For which of the following years the % of rise/fall in production from the previous year the maximum for company B?










  1. View Hint View Answer Discuss in Forum

    % rise/fall in production for company B in year = Production in current year - Production in previous year x 100
    Production in previous year

    Correct Option: B

    % rise/fall in production for company B in year = Production in current year - Production in previous year x 100
    Production in previous year

    % Rise in production for B in year 1992 = Production in current year 1992 - Production in previous year 1991 x 100
    Production in previous year 1991

    % Rise in production for B in year 1992 = 60 - 55 x 100
    55

    % Rise in production for B in year 1992 = 5 x 100
    55

    % Rise in production for B in year 1992 = 1 x 100 = 9 %
    11

    Similarly calculate for the 1993, 1994 , 1995, 1996 years from above formula and compare the result.


  1. What is the difference between the production of company C in 1991 and the production of company A in 1996?










  1. View Hint View Answer Discuss in Forum

    Difference of production of C in 1991 and A in 1996 = Production of company A in 1996 - Production of company C in 1991

    Correct Option: C

    Difference of production of C in 1991 and A in 1996 = Production of company A in 1996 - Production of company C in 1991
    Difference of production of C in 1991 and A in 1996 = ( 50 - 45 ) million tonnes = 5 x 1000000 = 5000000 ( Since 1 million = 10 lacks )

  1. What is the difference between the average production per year of the company with highest average production and that of the company with lowest average production in Million tonnes?










  1. View Hint View Answer Discuss in Forum

    Average production of A = 50
    Average production of B = 54.17
    Average production of C = 50

    Correct Option: C

    Average production of A = 50
    Average production of B = 54.17
    Average production of C = 50
    Difference of production = 54.17 − 50 = 4.17.

  1. What is the percentage increase in production of company A from 1992 to 1993?










  1. View Hint View Answer Discuss in Forum

    Percentage increase = Production of company A in 1993 - Production of company A in 1992 x 100
    Production of company A in 1992

    Correct Option: A

    Percentage increase = Production of company A in 1993 - Production of company A in 1992 x 100 %
    Production of company A in 1992

    Percentage increase = 55 - 40 x 100
    40


    Percentage increase = 15 x 100 = 37.5 %
    40
