the distribution instructions (lets assume by the father) are incomplete
He only allocates 94% of his wealth, or in other words 17/18 of his wealth
لو وحدنا المقامات للنص و التلت و التسع، و جمعناهم، ما بيتمو مية في المية، و لكن بيكونو ناقصين:
½ = 9/18
1/3 = 6/18
1/9 = 18 /2

Total: 17 / 18

8.5 + 5.67 + 1.89
It so ‘happens’ that the father’s wealth can be described by the number 17. So by adding 1 camel to the 17, we get to a total which, if 1/18 is left out, seeks to distribute the actual number of camels. In other words, this scheme works if the instructions for distribution leave out 1 / n, and then try to distribute a wealth of n+1.

For example: Father wants to leave 14 camels. Instructs that 1st son gets ½ (= 7.5/15), second gets 1/3 (+5/15), third gets 1/10 (=1.5/15). Okay, same problem, don’t want to split camels. Again total of shares is not 15/15 but only 14/15. Now the wise mathematician can again add one camel. Now total is 15 camels, out of which 14 are distributed following the instructions of inheritance.

In summary, it is genius what he did, but in my view not for the obvious reason people quote, but because the inheritance was not distributed following the instructions given

thanks for the brain teaser :)
