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

Let the expenditure for company X be x.
And for company Y be y.
Then for co. X 3xy/y*100=65.
300x100y = 65y.
300x =165y.
x/y = 165/300.
For co. Y
4xy/y*100 = 50.
400x100y = 50y.
400x = 150y.
Now equal x value to get y value.
co. X = (165/300)4 = 660/1200.
co. Y = (150/400)3 = 450/1200.
Thus we get x:y = 22:15.
So answer should be 22:15 not 15:22.
And for company Y be y.
Then for co. X 3xy/y*100=65.
300x100y = 65y.
300x =165y.
x/y = 165/300.
For co. Y
4xy/y*100 = 50.
400x100y = 50y.
400x = 150y.
Now equal x value to get y value.
co. X = (165/300)4 = 660/1200.
co. Y = (150/400)3 = 450/1200.
Thus we get x:y = 22:15.
So answer should be 22:15 not 15:22.

Where did that  sign went and how that 165 came there?

Why you have taken 3x150? According to the problem 3x 165. Please explain this.

Above method seems to be erroneous. 1 is not accounted.

Where does the 1 goes.
