In the number line, are x and y on different sides of zero point?
1). The distance from x to zero is equal to the distance from y to 1
2). The sum of the distance from x to zero and the distance from y to 1 is less than 1
Answer: E
From statement (1): |x-0|=|y-1|
x = y-1
x = 1-y ....hence insufficient
From statement (2): |x-0|+|y-1| less than 1
= x+y-1 less than 1
= x+1-y less than 1
= -x+y-1 less than 1
= -x+1-y less than 1 ....hence insufficient
Taking statements (1) and (2) together: still insufficient
