13.543 years ( approx )

Step-by-step explanation:

Here, the principal amount = 20,000

Annual rate of interest = 7 %

Let the amount will be $ 50,000 after t years,

The total compounded amount after t years = $ 50000

$\implies 20000(1+\frac{7}{100})^t=50000$

$\implies 2(1+0.07)^t=5$

$\implies (1.07)^t=2.5$

By taking log on both sides,

$\implies t log (1.07)=log(2.5)$

$\implies t=\frac{log(2.5)}{log(1.07)}$

$\implies t=13.5428471\approx 13.543\text { years}$
