Well, get a random number from 0 to 10, multiply if with 20 and add 25 – ByteHamster Aug 29 '16 at 10:06

Random rnd = new Random();
....
int x = rnd.Next(11)*20 + 25; // or .Next(10), if 225 is exclusive

1@AlexD Nope - `rand.Next(10)` picks number from `0..9`. It should be `Next(11)` :) – pwas Aug 29 '16 at 09:30

Create an array of the acceptable values. i.e. 25,45,65, ... 255. Use a random generated number to access the indexes of the array. Get the value at that array index. Happiness and joy abound in the world.
