    The ratio between the number of sides of two polygons 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, \[\frac{360}{2n}+4y=180\]                                ?(i) \[\frac{360}{n}+3y=180\]                                  ?(ii) Solving above equations, we get 0 = 5 So, number of sides are respectively 10 and 5.
