Check whether the following statement is true or not:

p : If x and y are odd integers, then x + y is an even integer.

Let us Assume that p and q be the statements given by


p: x and y are odd integers.


q: x + y is an even integer


since the given statement can be written as :


if p, then q.


Let p be true . then,


x and y are odd integers


x = 2m+1, y = 2n+1 for some integers m,n


x+y = (2m+1)+(2n+1)


x+y = (2m+2n+2)


x+y = 2(m+n+1)


x + y is an integer


q is true.


Therefore, p is true q is true


Hence, “if p, then q “ is a true statement.”
