A7:20Correct AnswerIncorrect Answer
B5:12Correct AnswerIncorrect Answer
C2:5Correct AnswerIncorrect Answer
D3:8Correct AnswerIncorrect Answer
ENone of theseCorrect AnswerIncorrect Answer
Solution
Let the ratio of A’s and B’s investment be x:y. The ratio of time periods of investment of A, => [4x/(4x+5y)] x 120000 = 30000 => [4x/(4x+5y)] = 1/4 => 16x = 4x + 5y => 12x = 5y => x:y = 5:12
