1) If the amounts invested by the two companies in 2005 were equal, what was the ratio of the total income of Company A to that of B on 2005? A) 31:33 B) 33:31 C) 34:31 D) 14:11 E) None of these Answer: Option CExplanation:Let the investment of each in 2005 be x. Then (Income of A) : (Income of B) = (x + 70% of x) : (x + 55% of x) '.' Income = (Investment) + (Profit) = (x+70x100):(x+55x100) = 17x10:31x20 = 34:31
