The correct option is D There was no loss or profit
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 $.
∴ Percent Profit/Loss of companies M and N together
% Profit/Loss =(85−8585×100)=0%
Thus, there was neither loss nor profit for companies M and N together.
