    Two different container contains \[(2{{x}^{3}}+2{{x}^{2}}+3x+3)L\] and \[(4{{x}^{3}}-2{{x}^{2}}+6x-3)L\] water. What is biggest measure that can measure both quantities exactly?

    A)  \[({{x}^{2}}+2x)L\]          

    B)  \[(2{{x}^{2}}+3)L\]          

    C)  \[(2x-1)L\]    

    D)  \[(x+1)L\]

    Correct Answer: B

    Solution :

    Capacity of both the containers is \[(2{{x}^{3}}+2{{x}^{2}}+3x+3)\,L\] and \[(4{{x}^{3}}-2{{x}^{2}}+6x-3)\,L\] i.e., \[(2{{x}^{2}}+3)\,(x+1)\,L\] and \[(2{{x}^{2}}+3)\,(2x-1)\,L\] Required measure is the H.C.F. of capacity of both the containers i.e., \[(2{{x}^{2}}+3)\,L\]
