How many odd integers are greater than the integer x and less than the integer y ?

(1) There are 12 even integers greater than x and less than y.

(2) There are 24 integers greater than x and less than y.


stmt 1......
We can consider examples of x & y which can have even integer difference...

So we can have the possible combinations:

X Y
4 10
E=2
O=3
5 9
E=2
O=1
4 9
E=2
O=2
5 10
E=2
O=2

Hence Insuff

stmt 2 :

Difference can be considered some even number less than 24...Lets assume this number as 6
Only possible combinations are:
X Y
4 11
O-3
5 12
O-3


Suff
