Let the principal amount be $ P $.
The sum amounts to five times itself, so the final amount is:
$ A = 5P $
Using the simple interest formula:
$ A = P + SI $
$ 5P = P + \frac{P \times R \times T}{100} $
Substituting $ R = 16\% $:
$ 5P = P + \frac{P \times 16 \times T}{100} $
Dividing by $ P $ on both sides:
$ 5 = 1 + \frac{16T}{100} $
$ 5 - 1 = \frac{16T}{100} $
$ 4 = \frac{16T}{100} $
$ T = \frac{4 \times 100}{16} $
$ T = 25 $ years
Final Answer:
$ \boxed{25} $ years
