- Question
A sum of money invested at simpleinterest triples itself in 8 years. How many times will it become in 20 years time?
Options- A. 8 times
- B. 7 times
- C. 6 times
- D. 9 times
- Correct Answer
- 6 times
ExplanationA = P(1 + rt/100)
So, A= 3P (it becomes triples)
3P = P(1 + 8r/100)?r = 25%
Now, when t = 20
?A = P(1 + 25*20/100)
?A = P(1+ 5)?A = 6P
So, it becomes 6 times.
