Answer is A

From 1 it is evident that r>4 so anything negative will add to bring the sum to 4

From 2 4 is greater than s but it does not s give any evidence that whether s is less than 0 it mat be or may be not

answer A as well. Statement 1 is sufficient since S has to be less than 0 in order for the equation to hold. answer YES
Statement 2 is not sufficient since we can have different values less or greater than 0 so the answer is YES/NO therefore insufficient.

Answer A
