stmt 1: this is possible if greatest & smallest have same sign i.e both +ve or both -ve so if both are +ve then the product is +ve if both are -ve then the product is +ve only if there are an even nos of terms

INSUFF

stmt2 : even nos of terms can be +ve ,-ve , both so product can be +ve or -ve ISUFF

combine:

gratest & smallest have same sign & theer are an even nos of terms

hence product will always be +ve( even nos of time -ve multiplication = +ve)

SUFF

Samir

I'm not convinced Samir....

combining the statements..
gratest & smallest have same sign & there are an even nos of terms

if the numbers are:
2, 4, 6, 8 then SUFF

and if the numbers are:
2, 4, -6, 8 then INSUFF... isnt it...

Suyog

its is given the product of the smallest and greatest integer is positive. In ur eg. smallest number is -6 and largest is 8. So the product is not positive. You have taken a wrong set of numbers.

Samir is correct in his explaination.
