${\green{\underline{\underline{\bold{Solution:-}}}}}$

Let the original number be x

According to the question:-

$x + 25\% \: of \: x = 400 \\ \\ \implies x + \frac{25}{100} \times x = 400 \\ \\ \implies \frac{100x + 25x}{100} = 400 \\ \\ \implies \frac{125x}{100} = 400 \\ \\ \implies125x = 400 \times 100 \\ \\ \implies125x = 40000 \\ \\ \implies x = \frac{40000}{125} \\ \\ \implies x = 320$

Hence,

$\boxed{The\:required \:number = 320}$
