Data Sufficiency

x, y, z are numbers on the number line. Is x < y < z ?

1). |y-x| + |y-z| = |z-x|
2). x<z

OA-E

x, y, z are numbers on the number line. Is x < y < z ?

1). |y-x| + |y-z| = |z-x|

i.e distance between y & x + dis bet y & z = dis bet z & x

This has possibilties i.e xyz or zxy(y should be on the way from x to z or vice versa) NOT SUFF

2). x<z

this states that x < z but x may be greater than or less than y

INSUFF

combine we have

xyz or zxy & x<z

hence x<y<z

Ans should be C

Arocks can you confirm that the ans is E.

i.e xyz is the combination so x<y<z

thanks a lot....
to confirm - the OA is mentioned as E...but the OA's can be slightly off at times...
