    In the given figure if parallel lines, EF, GFL, IJ are intersected by transversals. \[l\]and m. Where \[\mathbf{EG}=\mathbf{3}\text{ }\mathbf{cm},\mathbf{GI}=\mathbf{2}\text{ }\mathbf{cm},\text{ }\mathbf{FH}=\mathbf{6}\]cm, then HJ is

    A)  8 cm                           

    B)  9cm

    C)  12cm                          

    D)  4cm

    Correct Answer: D

    Solution :

    (d): \[\therefore \] \[EF\parallel GH\parallel IJ\] \[\therefore \]\[\frac{EG}{GI}\text{=}\frac{FH}{HJ}\] \[\therefore \]\[HJ=\frac{FH\times GI}{EG}=\frac{6\times 2}{3}=4\]cm
