Question
Ashish started a business by investing Rs. 6300. Few
months later; Ramesh joined him by investing Rs. 8000 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?Solution
Let the number of months for which Ramesh invested his money = ‘Y’ months Ratio of profit shares of Ashish and Ramesh = (6300 × 12):(8000 × Y) = 75600:8000Y = 189:20Y Let profit share of Ramesh be Rs. ‘100a’ So, profit share of Ashish = 1.05 × 100a = Rs. ‘105a’ ATQ; (189/20Y) = (105a/100a) So, Y = 9 Therefore, Ramesh joined the business (12 – Y) = 3 months after Ashish.
