Ameen invested Rs. 70,000 to start a business. After six months, Rahim joined with Rs. 1,05,000, and another six months later, Sameer entered the business with Rs. 1,40,000. After three years from Ameen's initial investment, in what ratio should the profit be divided among Ameen, Rahim, and Sameer?

Explanation

To find the profit-sharing ratio, multiply each partner's investment by the duration (in months) they were invested. Ameen's investment duration is 36 months, Rahim's is 30 months, and Sameer's is 24 months. Therefore, the ratio is (70000 × 36) : (105000 × 30) : (140000 × 24) which simplifies to 12:15:16.
