Answer : Option D
Explanation :
Let the expenditure of Company R in 2000 be x million US $.
Then, expenditure of Company R in 2001 = [ \( [\frac { 120 } { 100 } \) x x ] million US $
\( \frac { 120 X } { 100 } \) = 45 
x = 37.5.
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 = \( \frac {(I -37.5) } { 37.5} \) X 100 [ 
%Profit in 2000 = 10%]
I - 37.5 = 3.75
I = 41.25
i.e., Income of Company R in 2000 = 41.25 million US $.
