The only integers that astisfy

8  <   x   <  12

are 9, 10, and 11, because they are the only whole nubers, such
that 8 is less than all of them, and they are all less than 12.


The only integers that satisfy

12   <  y   < 15 

are 13 and 14,  because they are the only whole nubers, such
that 12 is less than all of them, and they are all less than 15.

If x is 9 and y is 13, then xy = 117 
If x is 9 and y is 14, then xy = 126
If x is 10 and y is 13, then xy = 130
If x is 10 and y is 14, then xy = 140
If x is 11 and y is 13, then xy = 143
If x is 11 and y is 14, then xy = 154

You can pick any of those 6 numbers for one possible value of xy.
