Find the amount on Rs. 6000 at 8% per annum compound interest for 3 years. MCQ with Answer and Explanation

Explanation:
Effective rate of compound interest for 2 years at 10% = 10 + 10 + (1010)/100 = 21%. Simple interest rate = 10 * 2 = 20%. Given 21% of sum = 441 => 1% of sum = 21. Simple Interest = 20% of sum = 20 * 21 = Rs. 420.

Explanation:
Half-yearly rate 5%, n=2. A = 5000 × (1.05)² = 5000 × 1.1025 = 5512.50, CI = 5512.50 − 5000 = Rs. 512.50.

Explanation:
Quarterly rate 2.5%, (1.025)⁴ = 1.10381289, effective = 10.3813% ≈ 10.38%.
