    The ratio of A to B is x : 8 and the ratio o B to C is 12 : z. If the ratio of A to C is 2 1, then what is the ratio of x : 2 ?

    A) 2 : 3                             

    B) 3: 2

    C) 4: 3                  

    D) 3: 4

    Correct Answer: C

    Solution :

    Given, \[A:B=x:8,\] \[B:C=12:z\] \[\Rightarrow \] \[A:C=\frac{A}{C}=\frac{A}{B}\times \frac{B}{C}=\frac{x}{8}\times \frac{12}{z}=\frac{3x}{2z}\] But       \[A:C=2:1\] \[\Rightarrow \] \[\frac{3x}{2z}=\frac{2}{1}\] \[\Rightarrow \] \[x:z=4:3\]
