Given information:
- Simple interest on a certain sum of money after 3 1/8 years is 1/4 of the principal.

To find:
- Rate of interest per annum.

Solution:
Let the principal be P and the rate of interest be R.

Simple interest = (P * R * T) / 100
Where T is the time in years.

Given, T = 3 1/8 years = 25/8 years
Simple interest = 1/4 * P

Substituting the values in the formula, we get:
( P * R * 25/8 ) / 100 = 1/4 * P

Simplifying the equation, we get:
R = 8%

Therefore, the rate of interest per annum is 8%.

Conclusion:
The rate of interest per annum for the given sum of money can be calculated using the formula for simple interest. Substituting the given values, we get the rate of interest as 8%.
