1. xyz <0
2. xy <0
here different cases are possible.
1)xyz<0 x=+ve, y=+ve z=-ve, in this z won't lie between x and y. ( try diff. combinations).
x=+ve, y=-ve, z=+ve in this case also z won't lie between x and y.
x=-ve, y=+ve, z=+ve in this case z may lie between x and y.
hence 1 alone is not sufficient to answer the question.
2) xy<0, x=+ve and y=-ve, or x=-ve and y=+ve
now as no information is provided by z hence 2 alone is also not sufficient to answer the question.
combining 1 and 2.
x=+ve, y=-ve and z =-ve, z won't lie b/w x and y.
x=-ve, y=+ve, z=+ve z may lie between x and y.
as even after combining 1 and 2 we are not able to get the unique solution hence answer should be
E.O Excellence... my search for you is on... you can be far.. but not beyond my reach!
