Let, the capital be x taka Earns on 3% rate = (x/4) × 3/100 = 3x/400 Earns on 5% interest = (2x/3) × 5/100 = x/30 Remainder = x - (x/4) - (2x/3) = x{1 - (11/12)} = x/12 Earns on 11% interest = (x/12) × (11/100) = 11x/1200 Total return = (3x/400) + (x/30) + (11x/1200) = (9x + 40x + 11x)/1200 = 60x/1200 = x/20 The average rate of return he earns on his total capital = {(x/20)/x} × 100% = 5%Related questions
