2/2=1, both are EVEN
3/3=1, both are ODD
so either both are ODD or EVEN
When Both are EVEN
p-r = EVEN
it means p & r are either both EVEN or ODD
q = EVEN
p + q + r = EVEN + EVEN + EVEN = EVEN
p + q + r = ODD + ODD + ODD = ODD
When both are ODD
p-r = ODD, q = ODD
it means either p is EVEN & r is ODD or opposite
p+ q + r = EVEN + ODD + ODD = EVEN or ODD + EVEN + ODD = EVEN
taking 1st equation
p-q-r = even
it mean one of them is even and two of them is odd
taking 1 & 2 both
p + q + r is EVEN
