    \[\Delta \]ABC and ADEF are similar. Also \[\angle A=\angle D\] and\[\angle B=\angle E\]. If 4AB = DE and BC = 12 cm, then EF is equal to:

    A)  3 cm               

    B)  24 cm

    C)  16 cm             

    D)  48 cm

    Correct Answer: D

    Solution :

     \[\therefore \Delta ABC~\sim \Delta DEF\] \[\Rightarrow \frac{AB}{DE}=\frac{BC}{EF}=\frac{AC}{DF}\Rightarrow \frac{1}{4}=\frac{12}{EF}\] \[\Rightarrow EF\text{ }=\]
