ATQ, Let Pawan’s initial capital be Rs. ‘x’. Then the initial capitals of Yamini and Zoya would be Rs. ‘x – 16000’ and Rs. ‘x – 40000’ respectively. So, (x) + (x – 16000) + (x – 40000) = 184000 3x – 56000 = 184000 x = Rs. 80000 So, initial capital of Pawan, Yamini and Zoya are Rs. 80000, Rs. 64000 and Rs. 40000, respectively. Profit sharing ratio between Pawan, Yamini and Zoya at the end of the year = [80000 × 12] : [64000 × 3 + 54000 × 9] : [40000 × 12] = 960000 : 678000 : 480000 = 160 : 113 : 80 ATQ, (113/353) × p = 2260 So, p = Rs. 7060
