(A) 2.5%
(B) 15%
(C) 20%
(D) 35%
(E) 40%


We can create the equation;

0.25p = 0.1q

25p = 10q

p/q = 10/25 = 2/5 = 40%.

Answer: E

Hi chetan2u,
In the question "If 25 percent of p is equal to 10 percent of q, and pq#0, then p is what percent of q ?" what is the role that "pq#0" plays. How does this information help/impact question.

hi probus,

say any one was 0, would have meant other is 0..
25% of p = 10% of q..
25% of 0 = 10% of 0
0=0....totally valid but doesnt make sense
as p is what percent of q becomes 0/0...
so pq not equal to 0 tells us that BOTH are different number and NOT 0

(A) 2.5%
(B) 15%
(C) 20%
(D) 35%
(E) 40%


\(\frac{p}{4} = \frac{q}{10} = 20\)(Say)

So, \(p = 80\) & \(q = 200\)

Thus, p in terms of q is \(\frac{80}{200}*100 = 40\)% , Answer must be (E)
