Answer:
12 years
Explanation:
The computation of the number of years is shown below:
Future value = Present value × (1 + rate)^number of years
where,
Present value = $100
Rate of interest = 6%
The future value = $200
$200 = $100 × (1 + 0.06)^number of years
2 = (1 + 0.06)^number of years
So after solving this, the number of years is 12 years
