ATQ, Let the initial investment of 'Pawan' and 'Qureshi' be Rs. '14x' and Rs. '21x', respectively Initial investment of 'Rita' = (8/7) × 21x = Rs. '24x' Ratio of profit share of 'Pawan', 'Qureshi' and 'Rita' = (14x × 24) :(21x × 20) :(24x × 16) = 28:35:32 Let the profit share of 'Pawan', 'Qureshi', and 'Rita' be Rs. '28y', Rs. '35y', and Rs. '32y', respectively. Profit share of 'Pawan' = '28y' = 7000 So, y = (7000/28) = 250 Difference between profit share of 'Qureshi' and 'Rita' = 35y 32y = 3y = 3 × 250 = Rs 750
