Solutions 1 to 5
1) Answer (c)
Total no. of electronic items in :
2009 = 6000 + 7000 = 13000
2010 = 9000 + 9400 = 18400
2011 = 13000 + 9000 = 22000 [MAX]
2012 = 11000 + 10000 = 21000
2013 = 8000 + 12000 = 20000
=> Total production is maximum in 2011

2) Answer (a)
Total production of LCD’s in 2011 = 9000
Total production of LCD’s in 2013 = 12000
Require ratio = 9000/12000 = 3 : 4
3) Answer (d)
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 + 1000 = 35,400
Average production of LCD’s over these four years = 35400/4 = 8850
=> Required Difference = 9750 – 8850 = 900
4) Answer (c)
No. of TV’s produced in 2009 = 6000
No. of TV’s produced in 2010 = 9000
=> Required ratio = 6000/9000 = 2 : 3
