ATQ, Let the sum invested by 'Arjun' be Rs. '4a'. So, sum invested by 'Karan' = 1.25 × 4a = Rs. '5a' ATQ; Ratio of profit shares of 'Karan' and 'Arjun' at the end of the year = (5a × 12) :(4a × 8) = 15:8 Let the profit earned by 'Karan' and 'Arjun' be Rs. '15b' and Rs. '8b', respectively. 15b - 8b = 10500 So, b = (10500/7) = 1,500 Profit share of 'Arjun' = 8b = 8 × 1500 = Rs. 12,000
