    The ratio in which Q divides the line segment joining P and R is

    A) 2:1

    B) 3:1

    C) 1:2

    D) None of these

    Correct Answer: B

    Solution :

    Let Q divides the segment PR in the ratio K : 1 Then,
    \[9=\frac{K\times 10+1\times 6}{K+1}\]
    \[9=\frac{10K+6}{K+1}\]
    \[9K+9=10K+6\]
    \[K=3\]
     Hence, the ratio will be 3 : 1
