Find the age of the three kids.
  1. The product of their ages is 36.
  2. Telling the sum of their ages would not help.
  3. The eldest of all is a programmer.
I know of all the controversies and lets see if we can have something here as well

Ages in ascending order : 2 units, 2 units, 9 units.

Here unit may be year, month, day or whatever shabbir had in mind while saying that the product is 36 (unit)³.




EDIT :: Controversy : Shabbir, you should mention whether the product of their ages is 36 year³ or month³ or day³ etc ... LOL
[ Of course in the later units, the oldest one cannot be a programmer ! ]

Forgot to mention the reason :

(1) Conclusions from "The product of their ages is 36." :
The ages of the kids can be :

`AGES######SUMS
1, 1, 36####x##38##x##[UNIQUE]
1, 2, 18####x##21##x##[UNIQUE]
1, 3, 12####x##16##x##[UNIQUE]
1, 4, 9##x##x##14##x##[UNIQUE]
1, 6, 6###x#x##13##x##[DUPLICATE]
2, 2, 9##x##x##13##x##[DUPLICATE]
2, 3, 6##x##x##11##x##[UNIQUE]
3, 3, 4##x##x##10##x##[UNIQUE]

(2) Conclusions from "Telling the sum of their ages would not help." :

As you can see above only we have one pair of duplicates for the sum 13. For all other sums, "Telling the sum of their ages would help" !

So, the kids ages can be 1, 6, 6 or 2, 2, 9.

(2) Conclusions from "The eldest of all is a programmer." :

Note the use of "The eldest" which means only 1 of them has the max. age.
So, 2, 2, 9 is the required triad of ages.
