    A. Answer: (3) 2011
    Explanation:-
    The maximum production of electronic item in 2011 = 13000 + 9000
    = 22000
    Then, the maximum production of electric item in 2011 is 23000.
    Hence, the answer is (3) 2011.


    B. Answer: (2) 900

    Explanation:-
    The total production of Tvs from 2009 to 2012 = 6000 + 9000 + 13000 + 11000
    = 39000
    Then, the average production of Tvs from 2009 to 2012 = 39000/4
    = 9750
    The total production of LCDs from 2009 to 2012 = 7000 + 9400 + 9000 + 10000
    = 35400
    Then, the average production of LCDs from 2009 to 2012 = 35400/4
    = 8850

    Then, the difference between average of production of Tvs and LCDs from 2009 to 2012  = 9750 – 8850 = 900

    Hence, the answer is (2) 900.

     

    C. Answer: (2) 2 : 3
    Explanation: –
    The total production of Tvs in 2009 = 6000
    The total production of LCDs in 2012 = 9000
    Then, the ratio of production of LCDs in the years 2009 and 2012 = 6000/900
    = 6/9 = 2/3 = 2 : 3
    Hence, the answer is (2) 2 : 3.

     

    D.Answer : (2) 3 : 4
    Explanation : –
    The production of LCDs in the year 2011 = 9000
    The production of LCDs in the year 2013 = 12000
    Then, the ratio of LCDs in the year 2011 and 2013 = 9000 / 12000
    = 9/12 = 3 : 4

    Hence, the answer is (2) 3 : 4.
