Stmt 2 does the exact same thing for Y.
Both stmts together also don't help in determining a definite value for X or Y. Hence E is the correct answer.
Hope this helps.
It's a little more complicated that this explanation. The problem is that the range of answers provided include values both less than and greater than 1.
(1) x < 8/9
no info about y, insuff.
(2) y < 1/8
no info about x, insuff.
To test them together, let's get a common denominator:
(1) x < 64/72
(2) y < 9/72
so, if we add both sides, we get:
x + y < 73/72
which means that x+y could be less than 1, equal to 1 or greater than 1: insufficient.
