1) X or Y could be of any value. Can't determine whether x+y = 7
(Insufficient)
2) even if x = 3 or y = 4, we don't know the value of another variable. Hence, can't determine whether x+y = 7
(Insufficient)
Answer is E

Is x+y=7?
(1) The sentence “x=3“and ”y=4” is incorrect.
insufficient
(2) Either x equals 3 or y equals 4.
insufficient
together
to make first 1 statement true ,if x =3,then y can't be 4 and if y=4 then x can't be 3
so
let's say x=3
then y is anything but 4....x+y is not =7 for sure
same with y=4
x is anything but 3..so x+y is not =7 again
IMO C
