    Question

    In triangle ABC, DE is parallel to BC. If AD = 3, DB =

    2, and DE = 5, what is the length of BC?
    A 2/3 Correct Answer Incorrect Answer
    B 5/3 Correct Answer Incorrect Answer
    C 10/3 Correct Answer Incorrect Answer
    D None of these Correct Answer Incorrect Answer

    Solution

    ATQ, By the Triangle Proportionality Theorem, AD/DB = DE/BC. So, 3/2 = 5/BC. Solving for BC, we get BC = 10/3.
