    The ratio between the numbers of sides of two polygon is \[2:1\]and the ratio between their Interior angle is\[4:3\]. The number of sides of these polygons are respectively:

    A)  8, 4                             

    B)  10, 5  

    C)  12, 6               

    D)         14, 7

    Correct Answer: B

    Solution :

     Here let side be \[2n\] and \[n\] so equation are             \[\frac{360}{2}+4y=180\]                                  ? (i)             \[\frac{360}{n}+3y=180\]                                  ? (ii) Solving above equation we get\[n=5\] So number of side are respectively\[10,\,\,5\].
