- Time period (T) = 9 months
- Rate of interest (R) = 10%
☯ Compounded Quarterly
To find
- Amount (A)
- Compound interest (CI)
Solution
- A = P (1+R/100)ᵗ
- A = ₹ 12800
- T = 9 months = 3 quarters
- R = ¹⁰⁄₄ % per quarter = ⁵⁄₂ % per quarter
- A = 12800 (1 +5/2×100)³
- A = 12800 × ⁴¹⁄₄₀ × ⁴¹⁄₄₀ × ⁴¹⁄₄₀
- A = 137842
☯ Amount = ₹ 137842
- CI = A - P
- CI = 137842 - 128000
- CI = 9842
☯ Compound interest = ₹ 9842
