Alfred started a business investing Rs. 45,000. After 3 months, Peter joined him with a capital of Rs. 60,000. After another 6 months, Ronald joined them with a capital of Rs. 90,000. At the end of the year, they made a profit of Rs. 16,500. Find the lire of each.

Clearly, Alfred invested his capital for 12 months, Peter for 9 months and Ronald

         for 3 months.

         So, ratio of their capitals = (45000 x 12) : (60000 x 9) : (90000 x 3)

                                             = 540000 : 540000 : 270000 = 2 : 2 : 1.

         Alfred's share = Rs. (16500 x (2/5)) = Rs. 6600

         Peter's share = Rs. (16500 x (2/5)) = Rs. 6600

         Ronald's share = Rs. (16500 x (1/5)) = Rs. 3300.
