यदि $X+Y=\left[\begin{array}{ll}7 & 0 \\ 2 & 5\end{array}\right]$ और $X-Y=\left[\begin{array}{ll}3 & 0 \\ 0 & 3\end{array}\right]$ है,तो $X$ और $Y$ ज्ञात कीजिए।

• A
  $X = \left[\begin{array}{ll}5 & 0 \\ 1 & 4\end{array}\right]$,$Y=\left[\begin{array}{ll}2 & 0 \\ 1 & 1\end{array}\right]$
• B
  $X = \left[\begin{array}{ll}5 & 0 \\ 1 & 4\end{array}\right]$,$Y=\left[\begin{array}{ll}2 & 0 \\ 1 & 2\end{array}\right]$
• C
  $X = \left[\begin{array}{ll}5 & 0 \\ 2 & 4\end{array}\right]$,$Y=\left[\begin{array}{ll}2 & 0 \\ 1 & 1\end{array}\right]$
• D
  $X = \left[\begin{array}{ll}4 & 0 \\ 1 & 4\end{array}\right]$,$Y=\left[\begin{array}{ll}3 & 0 \\ 1 & 1\end{array}\right]$
