Answer:
If 15 of them are negative, then the sign of their product will be negative...
If 12 of them are positive, then the sign will be positive
Remember, while solving questions like these, ignore the no. of positive integers...
If the no. of negative integers is even, all of them will cancel out, hence the answer is positive...
if the no. of negative integers is odd, then one remains negative, hence the product is negative...
