\underline{\textbf{Given:}}

\mathsf{0.23232323\;.\;.\;.\;.\;.\;.=\dfrac{x}{y}}

\underline{\textbf{To find:}}

\textsf{The sum of x and y}

\underline{\textbf{Solution:}}

\mathsf{Let\;\;p=0.23232323\;.\;.\;.\;.\;.\;.} --------(1)

\textsf{Multiply bothsides by 100}

\mathsf{100\,p=23.232323\;.\;.\;.\;.\;.\;.} -------------(2)

\mathsf{(2)-(1)\,\implies}

\mathsf{100\,p-p=23}

\mathsf{99\,p=23}

\implies\mathsf{p=\dfrac{23}{99}}

\textsf{As per given data, x=23 and y=99}

\mathsf{x+y=23+99=122}

\implies\boxed{\mathsf{x+y=122}}

\underline{\textbf{Answer:}}

\mathsf{Option\;(C)\;is\;correct}
