Income and Expenditure (in million US $) of five companies in the year 2001.
For Company R, if the expenditure had increased by 20% in year 2001 from year 2000 and the company had earned profit of 10% in 2000, what was the Company's income in 2000 (in million US $)?
35.75
37.25
38.5
41.25
Correct answer is D
Let the expenditure of Company R in 2000 be X million US $.
Then, expenditure of Company R in 2001 = ( (120/100) x x ) million US $
Therefore 120x/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 = (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 $.
