Interpreting the situation, it is found that:
-----------------------------------------
If you were to choose any 2 geniuses from the group, at least 1 of them would be younger than 15 years of age.
This means that at least 100 - 1 = 99 are younger than 15, that is, either 99 or all 100.
At least 1 of the math geniuses is older than age 15.
Thus 1 is older than 15, and the other 99 are younger.
