    The line\[\frac{x}{a}-\frac{y}{b}=1\]cuts the\[x-\]axis at P. The equation of the line through P perpendicular to the given line is:

    A)  \[x+y=ab\]        

    B)         \[x+y=a+b\]

    C)         \[ax+by={{a}^{2}}\]      

    D)        \[bx+ay={{b}^{2}}\]

    E)         \[ax-by=ab\]

    Correct Answer: C

    Solution :

    The equation of given line is \[\frac{x}{a}-\frac{y}{b}=1\] \[\Rightarrow \]               \[bx-ay=ab\] A line perpendicular to given line is \[ax+by=\lambda \] \[\therefore \]in the given options, option (c) is correct.
