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

7. 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

8. 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
