Explanation: For two years, compound interest minus simple interest equals P x r^2. Here the difference is Rs. 11,730 - Rs. 10,200 = Rs.

• A. Rs.7500
• B. Rs.7000
• C. Rs.8000
• D. Rs.6500
• E. None of these

Explanation: For two years, the excess of compound interest over simple interest is P x r^2. Thus Rs. 48 = P x (0.08)^2, so P = Rs. 48/0.0064 = Rs.

• A. Rs.20043.94
• B. Rs.18654.81
• C. Rs.20264.46
• D. Rs.19612.41
• E. None of these

Explanation: The simple interest equation gives Rs. 17,820 = Rs. 49,500 x r x 3, so r = 0.12, or 12% per year. Compound interest is Rs.

• A. Rs.500
• B. Rs.250
• C. Rs.5012.50
• D. Rs.5062.50
• E. None of these.

Explanation: From Rs. 500 = P x 5% x 2, the original principal is P = Rs. 500/0.10 = Rs. 5,000, so twice the principal is Rs. 10,000.

• A. Rs.2520
• B. Rs.3120
• C. Rs.3320
• D. Rs.2760
• E. None of these

Explanation: Apply each year's rate to the growing balance: Rs. 4,800 x 1.10 x 1.20 x 1.25 = Rs. 7,920. Therefore, the total compound interest is Rs.
