Answer: time = 55.48 years

Step-by-step explanation:

Given:

Principal amount = $10000

Interest rate = 2% p.a

Amount = $30000

We can evaluate the time taken using the following formula:


Amount=Principal(1+(r)/(100))^(t)


30000 = 10000*(1+(2)/(100))^(t)

Solving the above equation, we get


1.02^(t) = 3

Now taking log on both sides, we get;


t\ log(1.02) = log(3)

time = 55.48 years
