1.  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
E. 36.36

Answer: Option B

Explanation:

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

Then, income of Company in 2001 




=(110x x)million US $.
100

Therefore110x= 40     =>     x =(400).
10011









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   
E

 [Ref %Profit = 20% ]
=>     20 =[(400)- 1]x 100
11E

=>     E =400x100= 30.30.
11120

Therefore Expenditure of Company Q in 2000 = 30.30 million US $.
