Worksheet titled "Simple Interest Problems" with six word problems related to calculating simple interest, including examples with Euros, dollars, and percentages, designed for educational practice.

1. Interest = Principal × Rate × Time = 14,000 × 0.01 × 12 = 1,680 Euros.
2. Interest = 3,000 × 0.04 × 4 = 480 dollars; Total repayment = 3,000 + 480 = 3,480 dollars.
3. Interest = 3,900 × 0.06 × 3 = 702 dollars; Total balance = 3,900 + 702 = 4,602 dollars.
4. Let P be the principal. Interest = P × 0.04 × 5 = 0.2P. Total repayment = P + 0.2P = 1.2P = 4,800. So P = 4,800 / 1.2 = 4,000 dollars.
5. Interest needed = 2,400 - 1,500 = 900 dollars. Using I = P × R × T: 900 = 1,500 × 0.12 × T → T = 900 / (1,500 × 0.12) = 900 / 180 = 5 years.
6. Interest earned = 4,200 - 2,000 = 2,200 dollars. Using I = P × R × T: 2,200 = 2,000 × R × 10 → R = 2,200 / (2,000 × 10) = 2,200 / 20,000 = 0.11 or 11%.
