Answer:
11.526 years
Step-by-step explanation:
Let the investment or Principal be ' P' and it will be tripled in T years
Rate f interest ( R ) = 10 %
Amount = Triple the investment = 3P
We know that
Compound Amount = P[ 1 + R/100 ]^T
where each term indicates :
- P = Principal
- R = Rate of interest
- T = Time period
Substituting the given values
⇒ 3 = ( 1.1 )^T
As we cannot simplify further, let's take log on both sides
⇒ log 3 = log ( 1.1 )^T
⇒ log 3 = T × log 1.1
⇒ T = log 3 / log 1.1
⇒ T ≈ 11.526
Therefore it takes approximately 11.526 years to triple an investment at 10 % compounded annually.
