ATQ, Total Amount of P = Rs.'x' Total Amount of Q = Rs.4x/3 Interest received by P = x × {0.25 × 0.125 × 4 + 0.75 × (1.22 - 1)} = x × (0.125 + 0.33) = Rs.0.455x Interest received by Q = 4x/3 × (0.8 × 0.125 × 4 + 0.2 × (1.22 - 1)} = 4x/3 × (0.4 + 0.088) = 4x/3 × 0.488 = Rs.1.952x/3 Difference = 1.952x/3 - 0.455x = Rs.0.587x/3 Option I, x = Rs.12000 Difference = 0.587/3 × 12000 = Rs.2348 Option I is correct Option II, x = Rs.15000 Difference = 0.587/3 × 15000 = Rs.2935 Option II is correct Option III, x = Rs.18000 Difference = 0.587/3 × 18000 = Rs.3522 Option III is correct. Option IV, x = Rs.24000 Difference = 0.587/3 × 24000 = Rs.4696 Option IV is correct Hence, All of these are correct
