The following line graph gives the percent profit earned by two Companies X and Y during the period 1996  2001.
Percentage profit earned by Two Companies X and Y over the Given Years
%Profit =  Income  Expenditure  x 100 
Expenditure 
1.
The incomes of two Companies X and Y in 2000 were in the ratio of 3:4 respectively. What was the respective ratio of their expenditures in 2000 ?
Answer: Option
Explanation:
Let the incomes in 2000 of Companies X and Y be 3x and 4x respectively.
And let the expenditures in 2000 of Companies X and Y be E_{1} and E_{2} respectively.
Then, for Company X we have:
65 =  3x  E_{1}  x 100  65  =  3x   1 E_{1} = 3x x  100  .... (i)  
E_{1}  100  E_{1}  165 
For Company Y we have:
50 =  4x  E_{2}  x 100  50  =  4x   1 E_{2} = 4x x  100  .... (ii)  
E_{2}  100  E_{2}  150 
From (i) and (ii), we get:
E_{1}  = 

=  3 x 150  =  15  (Required ratio).  
E_{2} 

4 x 165  22

@Lavanya;
450/660 = 15:22.
Ways:
450/15=30,
So 30*22 = 660.
450/660 = 15:22.
Ways:
450/15=30,
So 30*22 = 660.

1 is added to 65/100 which then gives us 165/100.

@All.
Taking out the expenditure common the fraction becomes as I/E 1.

3x = 165.
4x = 150.
3x/165*150/4x = 15/22.
4x = 150.
3x/165*150/4x = 15/22.

Why am I getting 15/44  3/4*150/165  3/4*30/33  3/4*10/11  30/44?

Sorry for wrong answer.
15:22 is correct.
For co. X expenditure is 660.
For co. Y expenditure is 450.
Now co. X/co. Y = 450/660.
i.e. 15:22.
15:22 is correct.
For co. X expenditure is 660.
For co. Y expenditure is 450.
Now co. X/co. Y = 450/660.
i.e. 15:22.
