  1. $1.2$ years
  2. $1.11$ years
  3. $2$ years

  4. None

B Correct answer
Explanation

SI = (P * R * T) / 100. 50 = (500 * 9 * T) / 100. 50 = 45 * T. T = 50 / 45 = 10 / 9 = 1.11 years.

AI explanation

Using the simple interest formula, we substitute the principal of 500, the interest of 50, and the rate of 9% to find the time. The equation becomes 50 = (500 * 9 * T) / 100. Solving for T yields 50 = 45T, so T = 1.11 years.
