Data Sufficiency

you may want to check this problem.
it's clearly impossible to add two positive integers and get a fraction (like 75/100), so statement (2) has clearly been transcribed incorrectly.
that's such an obvious error that i don't think we'd see it even in the worst-quality materials ... so there's definitely no way that you'd see it on an official problem!

please check your sources and post back. thanks.

I thought the answer was A, but OA is D.
Can someone explian this ???

hi manishankar
see again in the problem
(2) it is (R/S)=75/100, you mistook (/, division) with (+) substraction
with this correction the problem is solvable one

ok, that makes a lot more sense. thanks for updating the problem.

with that new second statement, you can reduce to r/s = 3/4, which is the same as the first statement. therefore, each of the individual statements is sufficient.
