Simple and compound interest
Simple interest (solve for the interest, the principal, the rate or the time) and compound interest year by year.
Interest ₹1200, amount ₹6200
The working
- Simple interest SI = P × R × T ÷ 100.
- SI = 5000 × 8 × 3 ÷ 100 = 1200.
- The amount at the end is P + SI = 5000 + 1200 = 6200.
