Hello,
I need help with the following DS problem I faced in GMATPrep.
----
A certain list consists of several different integers. Is the product of all the integers positive?
1. The product of the greatest and the smallest of the integers in the list is positive.
2. There is an even number of integers in the list.
----
The OA is C, I picked E (after eliminating A/D/B easily), simply because I though even if the product of two numbers in a 4 number list is positive, even if 1 out of the remaining 2 numbers being negative will make the whole product negative.
Please advise on the chink in my logic. Thanks!
