Q. In the following question, two equations numbered I and II are given. Solve both the equations and mark the appropriate option:

I . \frac{12}{\sqrt{x}} - \frac{46}{\sqrt{4 x}} = 5 \sqrt{x}

I I . \frac{\sqrt{y}}{12} - \frac{10 \sqrt{y}}{24} = \frac{1}{\sqrt{y}}

Q. (i) If [1 1 x]

[\begin{matrix} 1 & 0 & 2 \\ 0 & 2 & 1 \\ 2 & 1 & 0 \end{matrix}] [\begin{matrix} 1 \\ 1 \\ 1 \end{matrix}]

= 0, find x.
(ii) If

[\begin{matrix} 2 & 3 \\ 5 & 7 \end{matrix}] [\begin{matrix} 1 & - 3 \\ - 2 & 4 \end{matrix}] = [\begin{matrix} - 4 & 6 \\ - 9 & x \end{matrix}]

x

y

are real numbers such that

\frac{1 + 3 i}{2 - 5 i} + \frac{1 - 5 i}{2 + 5 i} = x + y i
