1) K <0, but this does not say anything about m. When k = -2 and m = 3, k +m > 0 and when k = -2 and m = -1, K + m < 0.
Not Sufficient

2) km > 0. Both k and m are positive (k +m > 0 ) or both k,m are negative (k+m < 0) . Not sufficient

When you combine both statements, you can conclude that k < 0 (statement 1) and m <0 (from statement 2, km > 0, so if k <0, then m <0). So, k + m < 0.

My answer would be C.

from statement 1) k < 0, this doesn't provide us anything on m so it cannot help to decide. insufficient.

from statement 2) km > 0 this tells us that k and m are of the same sign. Both are either negative or positive. Doesn't help again. Insufficient.

Combined it tells us that k is negative and that km must be of the same sign so m is negative.

Sufficient.
