    If\[4\tan \theta =1\], find the value of\[\frac{4\sin \theta -2\cos \theta }{4\sin \theta +3\cos \theta }\]

    A)  \[\frac{1}{2}\]                                  

    B)         \[\frac{1}{6}\]   

    C)  \[\frac{2}{3}\]                                  

    D)         \[\frac{1}{3}\]

    Correct Answer: B

    Solution :

     We have 4 tan \[H.C.F.=\frac{\text{Product of the numbers}}{L.C.M.}\] Now, \[\text{5474}=\text{2}\times \text{7}\times \text{17}\times \text{23}\]\[\text{9775}={{\text{5}}^{\text{2}}}\times \text{17}\times \text{23}\]
