Quality of Data

Can you say what does this code print out?

var list = new int[]{1,2,3,4,5};
var delegates = list.Select(
   i => {
   var c = i * 10;
   return () => { Console.WriteLn(c); return c++; }
   }).ToList();

delegates.foreach( d => d() );
delegates[0]();
delegates[0]();
delegates[1]();

The answer is:
10
20
30
40
50
11
12
21
