Directions(6-10): Following graph shows the percentage profit gained by two companies A and B over the years 2008 to 2013.


6. If the expenditure of Company A in the year 2011 and 2012 was in the ratio 6 : 5, what was the ratio of its incomes?
   14 : 19
   13 : 10
   11 : 9
   13 : 11
   17 : 10
   Option B
   E1/E2 = 6/5
   So, E1 = 6 E2 = 5
   Now, I1 = E1*(100+30)/100 = E1*1.3
   I2 = E2*1.2
   I1/I2 = E1/E2*1.3/1.2
   = (6*1.3)/(5*1.2) = 78/60
   I1/I2 = 13/10 = 13 : 10

    

7. The income of Company A in the year 2012 and the expenditure of Company B in the year 2009 was the same, that is Rs.90 lakh. What will be the ratio of the income of Company B in 2009 to the expenditure of Company A in the year 2012?
   11:13
   9:5
   6:7
   2:9
   3:5
   Option B
   %( P)A = 20%
   (Expenditure)A = I/1.2 = 90/1.2 = 75 lakhs
   %(P)B = 35%
   (Income)B = 90 × 1.35 = 135 lakhs
   Ratio = 135/75 = 9/5

    

8. In which of the following years is the percentage of expenditure with respect to income is 80% for Company A?
   90%
   70%
   60%
   50%
   80%
   Option E
   Let the expenditure be x.
   Income = x*(100+25)/100 = 1.25x
   % = x/1.25x*100 = 100/1.25 = 80%

    

9. If the expenditure of Company B in the year 2010 was Rs. 40 lakh, what was its income (in Rs) in the year 2013?
