    The ratio of area of slice to the area of remaining pizza in (l) is:

    A) \[5:1\]

    B) \[1:5\]

    C) \[2:5\]

    D) \[5:3\]

    Correct Answer: B

    Solution :

    The angle subtended by a slice of pizza (l) at the centre is 600.
    Therefore, angle subtended by the remaining pizza at the centre is \[300{}^\circ \].
    \[\therefore \]Ratio of areas of minor sector and major sector
    \[=\frac{60}{360}\times \pi \times {{(6)}^{2}}:\frac{300}{360}\times \pi \times {{(6)}^{2}}\]
    So, option [b] is correct.
