Let a + b + c is even and we want to a * b * c is a multiple of 4 or not!If the sum of three integers is even, is the product of the three integers a multiple of 4 ?
(1) All three integers are equal.
(2) All three integers are even.
Now if we take 1, a = b = c and again it has to be that a + b + c is even so that means a, b and c have to be even. So each of a, b and c is multiple of 2. So a * b * c should be multiple of 4.
According to 2, it is clearly saying that a, b and c are even so we can easily incorporate the above logic here.
So D.

(1) All three integers are equal.
so all need to even so that sum is even, hence divisible by 4 SUFF
(2) All three integers are even.
same as above

Yop! U can also go with that, moneyman! It really depends whether u r able to break the Qs or not obvly in some limited time-period but not on the approach u r taking.
