    Solution

    ATQ, Ratio of profit share of ‘M’, ‘N’, and ‘O’, respectively = [(4x + 550) × 2 + 300]:[(5x + 450) × 2 + 250]:[(3x + 350) × 2 + 150] = (4x + 550 + 150):(5x + 450 + 125):(3x + 350 + 75) = (4x + 700):(5x + 575):(3x + 425) Desired profit = (5x + 575)/(12x + 1700) × 19200 = 5/12 × 19200 = Rs. 8000
