Re: If x is w% of y% of z, what percent of y is x? [#permalink]
If x is w% of y% of z, what percent of y is x?

(1) wz = 5000
(2) w = 2500 and z = 2

The statement tells us that:

X = (w / 100) * (y / 100) * z, and asks us what percentage is x of y?

In the given relationship it is sufficient to know the value of the product wz.

Then each one by itself.

This is a data sufficiency question. Options for DS questions are always the same.

The data sufficiency problem consists of a question and two statements, labeled (1) and (2), in which certain data are given. You have to decide whether the data given in the statements are sufficient for answering the question. Using the data given in the statements, plus your knowledge of mathematics and everyday facts (such as the number of days in July or the meaning of the word counterclockwise), you must indicate whether—

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 statements (1) and (2) TOGETHER are sufficient to answer the question asked, but NEITHER statement ALONE is sufficient to answer the question asked.
E. Statements (1) and (2) TOGETHER are NOT sufficient to answer the question asked, and additional data specific to the problem are needed.

I suggest you to go through the following post ALL YOU NEED FOR QUANT.

Hope this helps.

x=0.01w*0.01y*z
x=0.00001wyz

1-wz=5000--> x=0.05y (Sufficient)
2- w=2500, z=2-->x=0.05y (Sufficient)

Answer: D each statement alone is sufficient
