C :

#include<stdio.h>

void main(){
	int i,g,s,b;
	
	for(i=100;i<=999;i++){
		g=i%10;
		s=i/10%10;
		b=i/100; 
		if((g+s+b)%2==0&&b>s&&s>g){
			printf("%d\n",i);
		}
	}
}

C++ :

#include<iostream>
using namespace std;

int main() {
	int i;
	int g,s,b;
	for(i = 100;i <= 999;i++){
		b = i / 100;
		s = i / 10 % 10;
		g = i % 10;
		
		if((b+s+g)%2==0 && b>s && s > g){
			cout<<i<<endl;
		}
	}
}

Pascal :

var a,b,c,i:longint;
begin
for i:=100 to 999 do
begin
a:=i mod 10;
b:=i div 10 mod 10;
c:=i div 100;
if (b>a) and ((a+b+c) mod 2=0) and (c>b) then writeln(i);
end;
end.

Java :

public class Main {
	 public static void main(String[] args) {
		for(int i = 100;i<1000;i++){
			int a = i % 10;
			int b = i / 10 % 10;
			int c = i / 100;
			int d = a + b + c;
			if(c > b && b > a && d % 2==0){
				System.out.println(i);
			}
		}
	}
}

Python :

for i in range(100, 1000):
    bw = i // 100 % 10
    sw = i // 10 % 10
    gw = i % 10
    if (bw + sw + gw) % 2 == 0 and bw > sw and sw > gw:
        print(i)
