Best answer
Correct Answer - Option 1 : 8%

Formula used 

SI = (P × R × T)/100

SI = Simple interest

P = Principal

R = Rate

T = Time

Calculation

Let principal be 100Rs

⇒After 25 years principal = 300

⇒ SI = 300 - 100 = Rs.200

⇒ 200 = (100 × r × 25)/100

⇒ r = 8 %

∴ At 8 percent per annum simple interest, a sum of money triple itself in 25 yr
