Solution

Total no. of TV's produced from 2009 to 2012 = 6000 + 9000 + 13000 + 11000

=> 39,000

Average production of TV's over these four years = 39000/4 = 9750

Total no. of LCD's produced from 2009 to 2012 = 7000 + 9400 + 9000 + 10000 = 35,400

Average production of LCD's over these four years = 35400/4 = 8850

=> Required Difference = 9750 - 8850 = 900
