    months later; Ramesh joined him by investing Rs. 4800 such that at the end of the year, the profit share of Ashish was 5% more than that of Ramesh. How many months after Ashish did Ramesh join the business?
    A 3 months Correct Answer Incorrect Answer
    B 4 months Correct Answer Incorrect Answer
    C 2 months Correct Answer Incorrect Answer
    D 5 months Correct Answer Incorrect Answer
    E None of these Correct Answer Incorrect Answer

    Solution

    Let the number of months for which Ramesh invested his money = ‘Y’ months Ratio of profit shares of Ashish and Ramesh = (4200 × 12):(4800 × Y) = 50400:4800Y = 21:2Y Let profit share of Ramesh be Rs. ‘100a’ So, profit share of Ashish = 1.05 × 100a = Rs. ‘105a’ ATQ; (21/2Y) = (105a/100a) So, Y = 10 Therefore, Ramesh joined the business (12 – Y) = 2 months after Ashish.
