| Jul 15, 2014 at 18:00 | comment | added | Duncan | Step 1: Weigh W100 vs. B1. If B1 is heavier, you're done! If not... Steps 2-7: ???. Step 8: Profit! | |

| Jul 15, 2014 at 15:44 | comment | added | Kevin | "Since balls are numbered you don't have to compare balls of the same colour to each other using scale, you know the result already." Is this true for all possible weighings, or just 1-vs-1 weighings? Ex. Do I know that black balls 2 & 3 have a greater combined weight than black ball 4? | |
| Jul 15, 2014 at 14:48 | comment | added | klm123 | @PerManne, may be, may be not. This is not obvious for me. | |
| Jul 15, 2014 at 14:39 | comment | added | Per Manne | Doesn't that mean there is no point in weighing more than one ball against one ball (X = 1), since we will not get enough information to say much otherwise? For instance, the weight gap between two consecutive balls could be larger than the sum of all the other 199 gaps. | |

| Jul 15, 2014 at 14:30 | comment | added | klm123 | @PerManne, Yes, they have. No, any spacing is possible. | |
| Jul 15, 2014 at 14:28 | comment | added | Per Manne | Is it correct that the 201 balls all have different weights? If yes, are the 201 weights equally spaced, or could they be any 201 positive numbers? | |
| Jul 15, 2014 at 12:13 | comment | added | user88 | Oh, they're all numbered. Right, that makes things much easier. | |
| Jul 15, 2014 at 12:12 | comment | added | klm123 | @JoeZ., usual for this type of puzzle scales:They are called balance scale if I am not wrong. Colour is definitely relevant, please reread the question. | |

| Jul 15, 2014 at 11:42 | comment | added | user88 | Are we weighing the balls on a numerical or two-sided scale? Also, is the colour of the balls relevant to the question at all? (If not, then it would be easier just to say there are 201 balls.) | |
