The simple interest accrued on a sum of money at the end of four years...
To find the rate of interest per annum, we need to analyze the given information and use the formula for simple interest.

Let's break down the problem step by step:

Given:
- The simple interest accrued on a sum of money at the end of four years is 1/5th of its principal.

Formula for Simple Interest:
Simple Interest = (Principal * Rate * Time) / 100

Step 1: Understanding the information
The problem states that the simple interest accrued after four years is equal to 1/5th of the principal. This means that the interest earned is 1/5th of the initial amount (principal).

Step 2: Formulating the equation
Let's assume the principal amount is P.
According to the given information, the simple interest after four years is (1/5)P.

Using the formula for simple interest, we can write the equation as:
(1/5)P = (P * Rate * 4) / 100

Simplifying the equation:
1/5 = (4 * Rate) / 100
1/5 = Rate/25
Rate = (1/5) * 25
Rate = 5

Step 3: Finding the rate of interest
The rate of interest per annum is 5%.

Therefore, the correct answer is option B) 5%.
