    Equation of the plane parallel to the planes \[c+2y+3z-5=0,\text{ }x+2y+3z-7=0\]and equidistant from them is:

    A)  \[x+2y+3z-6=0\]

    B)  \[x+2y+3z-1=0\]

    C) \[x+2y+3z-8=0\]

    D)  \[x+2y+\text{ }3z-3=0\]

    E)  \[x+2y+3z-10=0\]

    Correct Answer: A

    Solution :

    All the given planes are parallel to each other but only\[x+2y+3z-6=0\]is equidistant from        \[x+2y+3z-5=0\]        and \[x+2y+3z-7=0\]having distance\[\frac{1}{\sqrt{14}}\].
