    A point C divides the join of P (1, 3) and Q (2, 7) in the ratio 3 : 4. The coordinates of C are

    A) \[(-2,-9)\]

    B) \[\left( \frac{10}{7},\frac{33}{7} \right)\]

    C) \[\left( \frac{3}{2},5 \right)\]

    D) \[\left( \frac{5}{3},5 \right)\]

    Correct Answer: B

    Solution :

    [b] Coordinates of C are \[\left( \frac{3\times 2+4\times 1}{3+4},\frac{3\times 7+4\times 3}{3+4} \right)\] i.e.,       \[\left( \frac{10}{7},\frac{33}{7} \right).\]
