Compound interest — amount
A = P(1 + R/100)ⁿ
Where: A = amount, P = principal (₹), R = rate of interest (% per year), n = time (years)
Solved example
Given: P = 7, R = 5, n = 10
Find: A (amount)
- Formula: A = P·(R/100 + 1)^n
- Substitute the values: A = 7·(5/100 + 1)^10
- Result: A = 11.402262
Answer: A = 11.402262
