$\Huge{\color{blue}{\fbox{\textsf{\textbf{Solution:-}}}}}$

$\large {\underline{\underline{\bold{\mathtt{Let, \: the \: \: other \: number \: be \: x }}}}}$

$\large {\underline{\underline{\bold{\mathtt{\color{blue}{According \: \: to \: \: the \: \: question,}}}}}}$

$\large \bold{x \: + 8.4 = 15.84}$

$\large \bold{ \implies \: x \: = 15.84 - 8.4}$

$\large \bold{ \implies { \boxed{ \mathtt{ \color{green}{\: x = \: 7.44}}}}}$

$\Large{\colorbox{yellow}{\underline{\underline{♣Answer♣:—\:\: 7.44} }}}$
