1. n+1>0
2. np>0


1. insuff, no info about p
2. insuff, n and p can be either both positive or both negative

together from I n>-1 so n >= 0
so n is either zero or positive
and from II we know is not zero so p>0

So C.

1) n > -1. No idea about p. Insufficient.
2) np > 0. Suggest both n and p are negative, or both n and p are positive. Insufficient.

Using both, we know n is negative, so p must be negative.

Ans C

I got this wrong, because I missed the point that n & p are integers.

Anyways, here's the correct solution.

1. n + 1 > 0. This means that n > -1. Insufficient
2. np > 0 We have no information about n, so can't conclude whether p is is positive or not.

Combining 1 & 2.

Since n & p are integers, thus n = {0, 1, 2, 3....}
np > 0 so, n has to be more than 0 {1, 2, 3....}

So, for the product to be positive, p has to be positive.

So, answer should be C
