Well, assuming it's Haskell (given the lack of semicolon and otherwise valid Haskell syntax):
x is an unused variable in the function "int" you're defining. This function returns the ratio (as a ratio, not a float) 5 / 3 for any argument, and is equivalent to "int = const (5 % 3)", which you would be more likely to see (probably inlined).
int x=5 % 3
and asking "What is the value of x?" Because a lot of jobs are CRUD and that form of programming rarely involves the modulus operator.
