There are 60 birds on a telephone wire and you get bored of bird watching and decide to hunt them.
No bird is colored other than red, yellow, or blue, although some birds may have more than one color.
You start off by shooting 1/2 the birds with red on them, followed by 3/4 of the birds with blue that remain. Then you shoot 1/4 of the birds with yellow that remain, and finally you shoot half of the birds with red that remain.
How many are left?
1 is left. There are three methods.
Method 1
This is too complex to explain but it uses x, y, Make Trade Fair, and 7 different languiges (if you can spell that correctly!)
Method 2
You don't neccessarily use a rifle. You fire a nuke at the wire. Obviously one has to have a radiation suit on, so it doesn't die.
Method 3 (I am so tired of typing that word!)
You "fire" a net into the air. One bird sees it. It flies and gets caught in it. Meanwhile you somehow make the wires touch together and the other birds get fried.
