The formula for the compound interest is -
\(P ( 1 + \frac{R}{100} )^T\)
Using this formula, we get the total amount
Here, P = 12000, R = R and T = 5.
We are given that after 5 years, the principal doubles so the total amount = 24000
\(24000 = 12000 \times ( 1 + \frac{R}{100} )^5\)
\(2 = ( 1 + \frac{R}{100} )^5\)
Now, we need to calculate the amount after 20 years.
So, Amount = \(12000 \times ( 1 + \frac{R}{100} )^{20}\)
As we know the value of \(( 1 + \frac{R}{100} )^5\), so breaking \(20 = 5 \times 4\)
= \(12000 \times (( 1 + \frac{R}{100} )^5)^4\)
= \(12000 \times (2)^4\)
= \(12000 \times 16\)
= 192000

In every 5 years, sum will double itself; Hence, in 20 (5*4) years, sum will be \(2^4\) times of the initial amount, that is 12000*16 = (160+32)*1000 = 192000
