For a triangle ABC, D and E are two points on AB and AC such that AD = $$\frac{1}{4}$$ AB, AE = $$\frac{1}{4}$$ AC. If BC = 12 cm, then DE is :
A. 5 cm
B. 4 cm
C. 3 cm
D. 6 cm
Answer: Option C
Solution(By Examveda Team)
According to question,By using B.P.T
$$\eqalign{ & \frac{{AD}}{{AB}} = \frac{{AE}}{{AC}} = \frac{{DE}}{{BC}} \cr & \frac{{AD}}{{AB}} = \frac{{DE}}{{BC}} \cr & \Rightarrow \,\frac{1}{4} = \frac{{DE}}{{12}} \cr & \Rightarrow DE = 3\,{\text{cm}} \cr} $$
