Each of the x, y and z represents a positive digit and x + y = z. If x < y, what is the value of y?

(1) z = 9
(2) y – x < 2



Calling a number a digit qualifies it to be an Integer?


Yes..
If we say a is a digit, it means a can be 0, 1,2, 3, 4, 5, 6,7 ,8 or 9 only and all these are integers too..
