If P and R are positive, is 25 percent of P equal to 10 percent of R?

(1) R is 150 percent greater than P
(2) P is 60 percent less than R.

For this question the I get the answer as C because we need both the equation to get the value of p and r.

Please let me know if there is another way of solving it .
Thanks in advance for your help

(1) R = 250% x P -> 10% R = 25% P Suff
(2) 40% x R = P -> 10% R = 25% P Suff

IMO, the answer should be D

This is how I interpret the question
(1) R is 150 percent greater than P : R = P + 150% * P = 250% P. Divide both side by 10 you have 10% x R = 25% x P -> Suff
(2) P is 60 percent less than R. : (100% - 60%) R = P or 40% x R = P. Divide both side by 4 you also have 10% x R = 25% x P -> Suff

Hope that helps

I solved it like this:

p/4 = r/10

1) p/4= 2.5p/10 = 10P SO P=P
2).4R/4=R/10 SO R=R

I think it should be D as well. From the stem, we are trying to find out if 0.25P = 0.1R. Statement (1) gives us R = 2.5P, and statement (2) gives us P = .4R, so either one is sufficient to figure out if 0.25P = 0.1R.

TO find the ratio is enough. Each statement alone is sufficient
