Answer:
y=9
Step-by-step explanation:
Given :
A = 25000
P = 20000
r % = 9.6 % = 0.096
n = 12
To Find :
The time taken say t.
Solution :
We know, compound interest is given by :
![A=P(1+\dfrac{r}{n})^{n.t}](https://tex.z-dn.net/?f=A%3DP%281%2B%5Cdfrac%7Br%7D%7Bn%7D%29%5E%7Bn.t%7D)
Taking log both sides :
![A=P(1+\dfrac{r}{n})^{n.t}\\\\log\ \dfrac{A}{P}= n.t\times log( 1+\dfrac{r}{n})\\\\t =\dfrac{1}{n}\times \dfrac{log\ \dfrac{A}{P}}{log(1+\dfrac{r}{n})}\\\\\\t=\dfrac{1}{12}\times \dfrac{log\ \dfrac{25000}{20000}}{log(1+\dfrac{0.096}{12})}\\\\\\t=2.33\ years](https://tex.z-dn.net/?f=A%3DP%281%2B%5Cdfrac%7Br%7D%7Bn%7D%29%5E%7Bn.t%7D%5C%5C%5C%5Clog%5C%20%5Cdfrac%7BA%7D%7BP%7D%3D%20n.t%5Ctimes%20log%28%201%2B%5Cdfrac%7Br%7D%7Bn%7D%29%5C%5C%5C%5Ct%20%3D%5Cdfrac%7B1%7D%7Bn%7D%5Ctimes%20%5Cdfrac%7Blog%5C%20%5Cdfrac%7BA%7D%7BP%7D%7D%7Blog%281%2B%5Cdfrac%7Br%7D%7Bn%7D%29%7D%5C%5C%5C%5C%5C%5Ct%3D%5Cdfrac%7B1%7D%7B12%7D%5Ctimes%20%5Cdfrac%7Blog%5C%20%5Cdfrac%7B25000%7D%7B20000%7D%7D%7Blog%281%2B%5Cdfrac%7B0.096%7D%7B12%7D%29%7D%5C%5C%5C%5C%5C%5Ct%3D2.33%5C%20years)
Hence, this is the required solution.
