A started a business with an investment of Rs.1500. After some months, B joins the business with an investment of Rs.3600 and after two more months C joins the business with Rs.2500. If the annual profit share of A and B is equal, then find for how many months C invested his money?
Let B joined after ‘x’ months. => 1500 x 12 : (12 - x) x 3600 : 2500 x (12 – x – 2) => 1500 x 12 : (12 - x) x 3600 : 2500 x (10 – x) => 1500 x 12 = (12 - x) x 3600 => 12 – x = 5 => x = 7 C invested his money = 10 – x = 3 months
