1, 6, 6.
There are 8 combinations { (1, 1, 36), (1, 2, 18), (1, 3, 12), (1, 4, 9), (1, 6, 6), (2, 2, 9), (2, 3, 6), (3, 3, 4) } of ages whose product is 36. After II hint of sum of ages, mathematician is unable to answer so there must be at least two combination of ages whose sum is same (Sum doesn’t matter) . Out of 8 combinations of ages only (1, 6, 6) and (2, 2, 9) have same sum.  Finally, III hint implies one is youngest so (2, 2, 9) is n’t possible as it has two youngest. So answer is (1, 6, 6)  which has elder twins.
