Dear GMATPrepNow Brent
Can you please shed light on this question. I do not know how answer would be D.
In Statement 1:
Let m=n=2..........x=24+16=40......then 40 is the greatest even number.
Let m=4 & n=2..........x=96+16=112......then 112 is the greatest even number.
It must insufficient.
In statement 2:
I can repeat same examples above and get same answers ...So insufficient
Answer must be E
What is the problem here? Can you help please?
Thanks in advance
I too have the same issue
