Answer:D Explanation:Total income of Companies M and N together = (35 + 50) million US $ = 85 million US $ Total expenditure of Companies M and N together = (45 + 40) million US $ = 85 million US $. Therefore Percent Profit/Loss of companies M and N together % Profit/Loss = ( 85 - 85 x 100 ) = 0%. 85 Thus, there was neither loss nor profit for companies M and N together.

Answer:A Explanation:Total income of all five companies = (35 + 50 + 40 + 40 + 50) million US $ = 215 million US $. Total expenditure of all five companies = (45 + 40 + 45 + 30 + 45) million US $ = 205 million US $. Therefore % Profit = [ (215 - 205) x 100 ] % = 4.88% ~= 5%. 205

Answer:D Explanation:The percentage profit/loss in the year 2001 for various comapanies are: For M = [ (35 - 45) x 100 ] % = -22.22% i.e., Loss = 22.22%. 45 For N = [ (50 - 40) x 100 ] % = 25% i.e., Profit = 25%. 40 For P = [ (40 - 45) x 100 ] % = -11.11% i.e., Loss = 11.11%. 45 For Q = [ (40 - 30) x 100 ] % = 33.33% i.e., Profit = 33.33%. 30 For R = [ (50 - 45) x 100 ] % = 11.11% i.e., Profit = 11.11%. 45 Clearly, the Company Q earned the maximum profit in 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 $)?

Answer:D Explanation: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 $.

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?

Answer:B Explanation: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 $.
