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

    2:5, profit at the end of the year is Rs.140000 and A’s share in it is Rs.40000, then what is the ratio of A’s and B’s investment?
    A 1:1 Correct Answer Incorrect Answer
    B 5:8 Correct Answer Incorrect Answer
    C 1:3 Correct Answer Incorrect Answer
    D 3:8 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, => [2x/(2x+5y)] x 140000 = 40000 => [2x/(2x+5y)] = 2/7 => 14x = 4x + 10y => 10x = 10y => x:y = 1:1
