ADRE 2024 • 2024 Paper 1Question 1
The total interest accrued on a Principal of ₹ 1000 over 1 year at compound interest of 10% per annum compounded 6 monthly, is:
A.₹ 105.20
B.₹ 102.20
C.₹ 102.50 ✓ (Correct)
D.₹ 105.50
Explanation: Half-yearly rate $r = \frac{10}{2} = 5\%$. Time $n = 2$ periods. $A = 1000 \left(1 + \frac{5}{100}\right)^2 = 1000 \times 1.05^2 = 1000 \times 1.1025 = 1102.50$. $CI = 1102.50 - 1000 = \text{₹ } 102.50$.
