Let the additional investments of Pawan, Bhanu and Raju be Rs. ‘7y’, Rs. ‘3y’ and Rs. ‘5y’ respectively. Ratio of proit share of Pawan: Bhanu: Raju = (9x + 9x + 7y) : (13x + 13x + 3y) : (11x + 11x + 5y) = 18x + 7y : 26x + 3y : 22x + 5y Proit share of Raju = {(22x + 5y)/(66x + 15y)} × 3240 = Rs. 1,080
