$\huge \color{purple}{ \colorbox{black}{answer}}$

T = 2 years 3 months =

$2 \: + \frac{3}{12} = 2 + \frac{1}{4} = \frac{9}{4}$

Let P be the principle amount

$\large \: a = p + { \frac{prt}{100} }$

$\large4491 = p(1 + \frac{11 \times 9}{4 \times 100)}$

$\large \: 4491 = p(1.2475)$

➪ P = 3600 Rs.

$\large \: si = \frac{3600 \times 11 \times 3}{100} = 1188 \: rs$

$\large{ \red {(amount = 3600 + 1188 \: rs)}}$
