Find the compound interest on ₹ 10,000 in one year at 4% per annum, the interest being compounded quarterly.
₹ 406.0401
Principal (P) = ₹ 10000
Rate (R) = 4% per annum which is 1% per quarter
Time (n) = 4 (as 1 year has 4 quarters in it)
Using the formula A = P × (1+R100)n, we have,
Amount = [10000 × (1+1100)4] = 10,406.0401
Compound Interest = Amount - Principal
∴ C.I. = ₹ (10,406.0401 - 10000) = ₹ 406.0401
