    Question

    ‘Ravi’ and ‘Sameer’ invested Rs. ‘y’ and Rs.

    ‘1.5y’ in a business respectively. After four months, both of them increased their investments to twice the original amount. If at the end of the year, the profit is divided in the ratio 7:9 respectively, find the value of initial investment made by ‘Sameer’.
    A Rs.180 Correct Answer Incorrect Answer
    B Rs.290 Correct Answer Incorrect Answer
    C Rs.513 Correct Answer Incorrect Answer
    D Can’t be determined Correct Answer Incorrect Answer
    E None of these Correct Answer Incorrect Answer

    Solution

    ATQ,

    Ratio of profit shares of ‘Ravi’ and ‘Sameer’ =

    {(y × 4) + (2y × 8) : (1.5y × 4) + (3y × 8)} = 4y + 16y : 6y + 24y = 20y : 30y

    ATQ;

    (20y / 30y) = (7 / 9)

    ‘y’ cancels out, hence we cannot determine the actual value of ‘y’.

    So, initial investment of Sameer = 1.5y, but value of y is not determinable.
