Question3 ; Marks:6 Prove that if m is even and n is odd, then m+n-2 is odd. Question3 ; Marks:6 Solution Question 1: (c) If m is even then wecan let m=2k (k is integer) If n is odd thenwe can let n=2p+1 (p is integer) now m+n-2 =2k+2p+1-2 =2(k+p)-1=even integer -1 = oddinteger hence if m is even and n is odd, then m+n-2 isodd..
