    If x : y = 1 : 3, y : z = 5 : k, z : t = 2 : 5 and t : x = 3 : 4, then what is the value of k?

    A) 1/2                   

    B) 1/3

    C) 2                                 

    D) 3

    Correct Answer: A

    Solution :

    Given x : y = 1 : 3,  y : z = 5 : k, z : t = 2 : 5 and       t :  x = 3 : 4 \[\Rightarrow \]   \[y:z=3:\frac{3k}{5},\] \[z:t=\frac{3}{10}:\frac{3}{4}\] And      \[t:x=\frac{3}{4}:1\] \[\therefore \]      \[\frac{3k}{5}=\frac{3}{10}\] \[\Rightarrow \]   \[k=\frac{1}{2}\]
