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
15.03% of (619.87 × 7) + (√399.63 × 16.11) ÷ 5 = ?
85.22 of 499.98% + 299.99 ÷ 30.18 = ?
(112.05 + 107.98) ÷ 11.04 + (12.05 × 4.99) ÷ 6 = ?
2090.03 ÷ 54.98 x 49.9 = ? + 20.32
244.98% of 189.98% of 599.99 + 199.98 = ?
620.15 + 1279.98 + ? × (4.79)2 = 149.95% of 1600.14
25.902 × 78.095 + 999.996% of 200.08 + 20.005 % of 7999.997 = ? × 15.008 × 33.009
