If I understand this an investment of Rs5662 was made at $r$ % interest for 6 months
and it resulted in Rs112 interest.

And you want to find the rate $r$?

Compounded monthly?

$\left(1+\dfrac{r}{12}\right)^6\times 5662 = 5774$

$\left(1+\dfrac{r}{12}\right)^6 = \dfrac{5774}{5662}$

$1+\dfrac{r}{12} = \left(\dfrac{5774}{5662}\right)^{1/6}$

$r = 12\left(\left(\dfrac{5774}{5662}\right)^{1/6}-1\right)$

$r = 0.03924 = 3.924\%$

n = 14th letter, t = 20th letter (6 from the end!).
