Whats is the ans for the below question???????

Variables X,Y,Z repesents positive numbers.X is directional proportional to Z.what is the value of X if Z =25

(1) Y=2 whenever Z=50

(2)X=2 whenever Z=100

(A)Statement (1) ALONE is sufficient ,but statement (2) alone is not sufficient to answer the question asked

(B)Statement (2) ALONE is sufficient ,but statement (1) alone is not sufficient to answer the question asked

(C)Both statement (1) and (2) together are sufficeint to answer the quetsions asked,but neither statements a;one is sufficient

(D)each statement ALONE is sufficient to answer the question asked.

(E)Statement (1) and (2) together are not sufficient to answer the question asked and additional data are needed.

Hi Ventakesh,

Please don't open threads for such questions.

As per your question,

Given x= k*z (k - constant)

z = 25, x = ?

1) Y is given. No use. Hence insufficient.

2) get value of k using x and z. Once we know k, we can find out the value of x given z=25. Hence sufficient.

Hence B.

Cheers!
