    Question

    If the ratio of time periods of investment of A and B is

    4:5, profit at the end of the year is Rs.150000 and A’s share in it is Rs.30000, then what is the ratio of A’s and B’s investment?
    A 5:12 Correct Answer Incorrect Answer
    B 5:16 Correct Answer Incorrect Answer
    C 5:9 Correct Answer Incorrect Answer
    D 5:8 Correct Answer Incorrect 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 150000 = 30000 => [4x/(4x+5y)] = 1/5 => 20x = 4x + 5y => 16x = 5y => x:y = 5:16
