Aman, Bhanu, and Chikku jointly initiated a business

Solution

ATQ, Let, the sum invested by 'Bhanu' be Rs. 'x'. So, the sum invested by 'Chikku' = 80000 - 24000 - x = Rs. 56,000 - x ATQ, Profit share of 'Aman' to 'Bhanu' = [24000 X 6 + (24000 + 8000) × 6]:[x × 8] = 7:6 Or, [(24000 + 32000) × 6]:[x X 8] = 7:6 Or, (56000 × 6) :(x × 8) = 7:6 So, [(56000 × 6) /( x × 8) ] = (7/6) Or, [(7000 × 6) /(x) ] = (7/6) Or, x = 7000 × 6 × (6/7) So, x = 36,000 So, the sum invested by 'C' = 56000 - x = Rs.20,000
