Pls correct me if I am wrong
In Question, provided that
1. Median of X,Y and Z is 76 which means Y is 76
2. Range of the numbers is 22 stating Z-X= 22
Compiling it would give X< 76< (X+22), where X can range from 55 to 75 to satisfy X<Y<Z Condition.
So Answer might be E

from (1), x = z - 22; not suf.
from (2), y = 76; not suf.
both (c): if z = 90, then x = 90-22 = 68 and y = 76; if z = 77, x = 55 and y = 76; more than one answer, not suf.
answer: (E)
