Correct Answer: 13,440


Solution : We have,
$A = 12000, r = 12\%, n = 1 $ (compounded annually) and $t = 3$ years.
$A = P \left(1+\frac{r}{100}\right)^{t}$
Substituting the given values into the formula,
$⇒12000 = P (1+\frac{12}{100})^{1×3}$
$⇒12000 = P (1.12)^{3}$---(i)
For $t = 4$ year
$⇒ A = P(1 + \frac{12}{100})^{4}$
$⇒ A = P (1.12 )^{4}$---(ii)
Divide equation (ii) by (i), we get
$⇒A = 12000×1.12 = 13440$
Hence, the correct answer is Rs. $13440$.
