Answer 2

$\huge{\underline{\underline{\mathcal{\red{Given\::}}}}}$

• $\sf{A\::\:55\::\:9\::\:11}$

${ }$

$\huge{\underline{\underline{\mathcal{\red{Find\::}}}}}$

• $\sf{Find\:value\:of\:A}$

${ }$

$\huge{\underline{\underline{\mathcal{\red{Solution\::}}}}}$

$\:\:\:\:\:\:\:\:\::\:\Longrightarrow\sf{\:\frac{A}{55}}\:=\:{\frac{9}{11}}$

$\:\:\:\:\:\:\:\:\::\:\Longrightarrow\sf{\:11\:A\:=\:9\:\times\:55}$

$\:\:\:\:\:\:\:\:\::\:\Longrightarrow\sf{\:11\:A\:=\:495}$

$\:\:\:\:\:\:\:\:\::\:\Longrightarrow\sf{\:A\:=\:{\frac{495}{11}}}$

$\:\:\:\:\:\:\:\:\::\:\Longrightarrow\sf{\:A\:=\:45}$

${ }$

• $\therefore\:{\underline{\sf{Hence,\:the\:value\:of\:A\:is{\:\bold{45}}}}}.$
