    How many pieces of equal size can be cut from a rope of 30 metres long, each measuring \[3\frac{3}{4}\]metres?

    A) \[8\]                       

    B)        \[10\]

    C) \[6\]                     

    D)        \[12\]

    Correct Answer: A

    Solution :

    Total length of the rope = 30 m. Length of each piece \[=3\frac{3}{4}m.\] Number of pieces \[=\frac{30}{3\frac{3}{4}}=\frac{30}{\frac{15}{4}}=30\times \frac{4}{15}=8\]
