    \[\Delta PQR\]and \[\Delta \,LMN\] are similar. If \[3PQ=LM\] and \[MN=9\text{ }cm,\]then QR is equal to

    A)  3 cm   

    B)  6 cm

    C)  9 cm   

    D)  12 cm

    Correct Answer: A

    Solution :

    [a] \[\Delta PQR\sim \Delta LMN\] \[\therefore \] All sides are proportional to their corresponding sides. \[\frac{PQ}{LM}=\frac{1}{3},\]\[MN=9\,cm\] \[\therefore \]\[QR=\frac{1}{3}\times 9=3\,cm\]
