    If the circle\[{{x}^{2}}+{{y}^{2}}-17x+2fy+c=0\]passes through (3, 1), (14, 1) and (11, 5), then c is:

    A)  0                                            

    B)  \[-\,41\]                             

    C)  \[\frac{-17}{2}\]              

    D)         41

    E)  \[\frac{17}{4}\]

    Correct Answer: D

    Solution :

    \[\because \]Circle\[{{x}^{2}}+{{y}^{2}}-17x+2fy+c=0\]passes through (3, 1), (14, 1) and (11, 5), then          \[2f+c=41\]                              ...(i)      \[2f+c=41\]                            ...(ii) and              \[10f+c=41\]          ...(iii) On solving Eqs. (i) and (iii), we get\[c=41,\]and\[f=0\]
