A little EQ and a little IQ

Below are two questions I gave to my candidates:

Question 1:
There are 15 visually identical balls. All of them have identical mass except for one. (You do not know whether it is heavier or lighter.) With a balance scale, can you identify the ball with different mass with just three weighing?
This is an EQ question. Do not spend more than 15 minutes on it. Also tell me how you found the answer.

Question 2:

If
1 = B
3 = BA
6 = CA
19 = CAB,

100 = ?

This is IQ question. Hint: There is no CAD or DAD.


Wanna try?
