Q.
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?
The correct answer is C
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 E1 and E2 respectively.
Then, for Company X we have:
65 =[( 3x  E1 )/E1]×100 =>65/100 = (3x/E1)  1
=> E1 = 3x×( 100/165 ) .... (i)
For Company Y we have:
50 = [(4x  E2 )/E2]x 100 =>50/100= (4x/E1)  1 => E2 = 4x×( 100/150 ) .... (ii)
From (i) and (ii), we get:
E1/E2=[3x ×(100/165)]/[4x×(100/150)]
E1/E2=15/22 (required ratio)

Q.
If the expenditure of Company Y in 1997 was Rs. 220 crores, what was its income in 1997?
The correct anwer is B as profit percent of Company Y in 1997 = 35.
Let the income of Company Y in 1997 be Rs. x crores.
Then, 35 =
x  220
x 100 x = 297.
220
Income of Company Y in 1997
= Rs. 297 crores.

Q.
If the expenditures of Company X and Y in 1996 were equal and the total income of the two Companies in 1996 was Rs. 342 crores, what was the total profit of the two Companies together in 1996? (Profit = Income  Expenditure)
The correct answer is D as ,
Total Income = 342 cr
Income in percentage = 140+145=285%
Expenditure per year= 200×342/285 = 240 cr
So total profit in 1996 = 342  240 = 102 cr.

Q.
If the incomes of two Companies were equal in 1999, then what was the ratio of expenditure of Company X to that of Company Y in 1999 ?
The correct answer is D
In 1999 , profit % of X = 50
profit% of Y = 60
Also , let their income in 1999 be i each and expenditure of X be x and that of Y be y.
For X ,
50 = (i  x)*100/x
1/2 = (i  x)/x
x/2 = i  x
i = 3x/2 (eq1)
For Y ,
60 = (i  y)*100/y
3/5 = (i  y)/y
3y/5 = i  y
i = 8y/5(eq 2)
Equating eq 1and 2 , we get
3x/2 = 8y/5
x/y = 16/15
x : y = 16:15
