Please Explain
If x and y are nonzero integers, is (x-1 + y-1)-1 > [(x-1)(y-1)]-1 ? (1) x = 2y (2) x + y > 0 Please see my analysis below.Rephrased the question as Is xy/x+y > xy?? (1) INSUFFICIENT. Substituted x=2y in the equation which leads to the equation ((2y^2)/(3y))>(2y^2) which means 1/3y >1 When y=-2 and ...

Brent: Can you please explain how statement 2 is sufficient? Statement 2: w = max(10, w) If w = max(10, w), then w is the larger value. In other words, w is greater than or equal to 10 If w is greater ,then we can conclude that min(10, w) = 10 If w is equal, then how can we conclude min(10,w) =10?? ...

Both the statements are SUFFICIENT.
(w,v) lie in the fourth quadrant where w>0 and v<0
Statement 1: (w,v) lies in quadrant 2. (w,v)doesn't lie in quadrant 4. SUFFICIENT.
Statement 2: w=-4<0 v=2>0 lies in quadrant 2.(w,v)doesn't lie in quadrant 4. SUFFICIENT.
D is the answer.

OG 11 Edition 65 problem
If m is an integer, is m odd?
1. m/2 is NOT an even integer
2. m-3 is an even integer
When I solved the problem both statements were valid. I chose D as the answer but the official guide has B as the answer.
Can anyone explain why statement 1 is NOT sufficient?
Thanks in Advance.

Thanks Mitch for the response. I have one more question here
Here in statement 1 there are 2 values for x.
x=z and x=2y.
Why did u only pick x=2y value? This is where I committed the mistake.
Thanks in advance for all your help.

Number Properties - Data Sufficiency Question
If x,y,and z are integers, is x Even?
(1) 10^x= (4^y)(5^z)
(2) 3^x+5= 27^y+1
From my analysis I think C should be the answer but A is the answer. Can anyone explain how statement 1 alone is sufficient?
