Q1:

If the income of Company Q in 2001 was 10% more than its income in 2000 and the Company had earned a profit of 20% in 2000, then its expenditure in 2000 (in million US $) was?

A 28.28

B 30.30

C 32.32

D 34.34

ANS:B - 30.30

Let the income of Company Q in 2001 = x million US $.

Then, income of Company in 2001 = ( 110 x x ) million US $.
100
Therefore 110x = 40     =>     x = ( 400 ) .
100 11
i.e., income of Company Q in 2000 = ( 400 ) million US $.
11
Let the expenditure of Company Q in 2000 be E million US $.
Then, 20 = [(400/11) - E] x 100     [Ref %Profit = 20% ]
E
=>     20 = [ ( 400 ) - 1 ] x 100
11E
=>     E = 400 x 100 = 30.30.
11 120
Therefore Expenditure of Company Q in 2000 = 30.30 million US $.
