According to the question: Initial investments of Raj, Sam, and Tina: Rs. 6x, Rs. 5x, and Rs. 4x respectively. Additional investments of Tina, Raj, and Sam: Rs. 2y, Rs. 3y, and Rs. y respectively. Ratio of their profits: (6x + 3y):(5x + y):(4x + 2y) = (9x + 3y):(6x + y):(8x + 2y) Profit share of Raj for being an active working partner = 0.30 × 2500 = Rs. 750 Profit share of Raj for his investment = 0.70 × 2500 × (9x + 3y)/(23x + 6y) = Rs. 750 Total amount of profit received by Raj = 750 + 750 = Rs. 1500
