Answer D

if X and Y are both integers and X < Y

USING 1)
x pow y = 4
is only possible when x = -2 and y = 2
sufficient

USING 2)
[X] = [Y] and x < y, this can only happen if X and Y are on opposite side Zero. For example Y=5, and X=-5
sufficient
X+y =0

1. x^y=4
2. x absolute = y absolute

it seems weird as obviously the only y that there is not Y which is less than X that satisfies either/both 1 and 2.....


Good question.

If x and y are integers and x<y, what is the value of x+y?

(1) x^y=4 --> as x and y are integers and x<y then only possible solution is (-2)^2=4 (other integer solutions for x^y=4 are: 2^2=4 and 4^1=4) --> x+y=-2+2=0. Sufficient.

(2) |x|=|y| --> as also x<y then they have opposite signs (x<0<y, so |x|=-x and|y|=y) --> -x=y --> x+y=0. Sufficient.

Answer: D.

The question has very simple fundamentals but it is still tricky, mainly because it gives you a part of the information in the question stem. We often forget to consider that when we are busy analyzing the statements.

x and y are integers
x < y
Question: (x + y) = ?

(1) x^y = 4
This can happen in a number of ways:
x= 2, y = 2
x = -2, y = 2
x = 4, y = 1
But in only one case, x < y. x must be -2 and y must be 2.
x + y = 0
Sufficient

(2) |x| = |y|
This can happen in two ways:
x = y (x and y have same sign and absolute value)
or x = -y (x and y have opposite signs and same absolute value)
Since x < y, x must be negative and y must be positive. (they both cannot be positive since their absolute value is the same but x < y)
In that case x = -y
x+y = -y+y = 0
Sufficient

Case 1....x^y = 4....Take y = 2, x = -2...x+y = 0......You cant take y=x=2 as y>x.
You cant take x = 4, y = 1 again y>x
Sum = 0

Sufficient.

Case 2 .... |x| = |y| only possible when x is -ve as y>x....so again sum = 0

Sufficient.

I really like this question, though i missed the right answer.
the kind of question testing the concepts. does not require any heavy calculation.
