Given : x,y,z are integers >1 (1)xyz=70 => xyz=5*7*2 => say 5,2,7 are values of x,y,z in any order hence x+y+z is answered =>SUFFI (2)x/yz =7/10 this can be any values for x,y,z say, x=7,y=5,z=2 or x=14,y=5,z=4 hence x+y+z will change INSUFFI

Bunuel, if the question states that x, y and z are greater then 1... then is ok to say that one of thoes is 1? as I read it , none of them can be one " GREATER THEN 1"???

Again: "If x, y and z are integers greater than 1 ..." So none of them is one. _________________

Bunuel,

The problem doesnt specifically state that the integers are unique or different. Is it possible for A to be insufficient as xyz to be 7*7*5 with a sum of 19 or the answer provided above with 2*5*7 and a sum of 14?

I'm assuming the variables need to be unique integer values, but this threw me off at first.
