Find the rate of Simple Interest when a sum of money treble itself in ...
Given, the sum of money trebles itself in 25 years.
Let the principal amount be P.

Formula:
Simple Interest = (P * R * T) / 100
where P is the principal amount, R is the rate of interest, and T is the time period.

Calculation:
After 25 years, the sum becomes 3P.

Using the formula of Simple Interest,
3P = P + (P * R * 25) / 100
2P = (P * R * 25) / 100
R = (2P * 100) / (P * 25)
R = 8%

Therefore, the rate of Simple Interest is 8%. Hence, option C is the correct answer.
