To find Shikha's balance after 3 years, we need to calculate the interest earned each year and account for her withdrawal.
Calculating Simple Interest
The formula for simple interest is:
Interest = Principal × Rate × Time
Here, the principal amount is Rs. 2000, the interest rate is 6% (or 0.06), and the time is in years.
Year 1
- Interest for Year 1: 2000 × 0.06 × 1 = Rs. 120
- Balance after Year 1: 2000 + 120 - 700 = Rs. 1420
Year 2
- Interest for Year 2: 2000 × 0.06 × 1 = Rs. 120
- Balance after Year 2: 1420 + 120 = Rs. 1540
Year 3
- Interest for Year 3: 2000 × 0.06 × 1 = Rs. 120
- Balance after Year 3: 1540 + 120 = Rs. 1660
Final Balance
After 3 years, Shikha's balance will be Rs. 1660.
