A company deposits \( \$ 200 \) in bank with an interest rate of \( 5 \% \). After how many years will the amount increase by \( \$ 50 \) with the same interest rate?
- A. 5
- B. 10
- C. 15
- D. 25
Step-by-step solution
Using simple interest formula I = P * r * t, with I = 50, P = 200, r = 0.05, we get 50 = 200 * 0.05 * t → 50 = 10t → t = 5 years.
