Answer 1

Imagine the combination as a number with 3 spaces, and you need to fill the spaces with the appropriate digits.
_ _ _
For the 1st place you can chose any number from 1,2,3,4,5,6,7,8,9,0 so there are a total of 10 choices.
Similarly for the 3rd place.
For the 2nd place, you can chose any number from 0, 1, 2 so you have three choices for it.

So the total number of combinations possible for the lock are: \[10\times3\times10 = 300\]
