A 35.75

B 37.25

C 38.5

D 41.25

ANS:D - 41.25

Let the expenditure of Company R in 2000 be x million US $.

Then, expenditure of Company R in 2001 = ( 120 x x ) million US $.
100
Therefore 120x = 45     =>     x = 37.5.
100
i.e., expenditure of Company R in 2000 = 37.5 million US $. Let the income of Company R in 2000 be I million US $.
Then, 10 = (I - 37.5) x 100     [ Ref %Profit in 2000 = 10%]
37.5
    => I - 37.5 = 3.75     => I = 41.25 i.e., Income of Company R in 2000 = 41.25 million US $.
