A sum of money invested at simpleinterest triples itself in 8 years. How many times will it become in 20 years time?

Question

Accepted Answer

A = 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.
