If r and s are positive integers, r is what percent of s?

(1) r = 3/4*s

(2) r + s = 75/100

from stmnt 1: r/s= 3/4, viz 75%

IMO A

Hello Bunuel. I don't understand how statement 2 is sufficient, can you help with an explanation? Prompt says r and s are positive integers so I determined St 2 is insufficient since their sum can't be a non-integer. Thanks in advance.

(2) reads r/s = 75/100. Edited. Thank you.

In that case D would be correct.
