Answer 2

$\large\tt{\colorbox{violet}{\colorbox{indigo}{\colorbox{blue}{\colorbox{green}{\colorbox{yellow}{\colorbox{orange}{\colorbox{red}{\colorbox{black}{ANSWER}}}}}}}}}$

$\tt \: SI = ₹90 \\ \\ \tt \: R = 4 \%\: \\ \\ \tt \: T = 2 \: years \\ \\ \tt P = ? \\ \\ \\ \tt SI = \frac{PRT}{100} \\ \\ \tt 90 = \frac{P \times 4 \times 2}{100} \\ \\ \tt \: P = \frac{\cancel{90} {}^{ \: 45} \times \cancel{100} {}^{ \: 25} }{\cancel4 \times \cancel2} = 45 \times 25 \\ \\ \tt \: P = \underline{ \underline{₹1125}}$
