1. r = 3/4 s --> r=0.75s ...ie. 75% s sufficient..
2. r+s = 75/100...this does not tell us r or s so we cant calculate r % of s...insufficient..

answer is A

I think there is something wrong here. If r and s both are positive integers how can
r+s=0.75 ?

well, I think the poster mistypes the condition, it maybe like r+s=75/100s or 75/100r
In this case, answer will be D

Precisely .. how can this be possible ? The question is definitely wrong.

May be it is r/s=75/100. i.e
r (divided by) s=75/100. Which means r=.75s.

Check the answer choice again too. May be you are not reading it right.

Answer to your question is A.

However, in OG if official answer is D, then in statement two, "plus" sign should have been "divide".

In OG, many times people gets confused between "plus" sign and "divide" operator. Thats font and printing problem.
