According to the question, 6000 – 5000 = (5000 × r × 24) ÷ (12 × 100) Or, 1000 = 100 × r Or, r = 10 When the sum is invested at compound interest, Effective rate of interest = (r + 20) ÷ 3 = (10 + 20) ÷ 3 = 10% Effective time period = 1 × 3 = 3 units Amount received = Principal × {1 + (r/100)}time period = 5000 × {1 + (10/100)}3 = 5000 × (1.1)3 = 6655
