Data Sufficiency (DS) | When all the boxes in a warehouse were arranged in stacks of 8, there

Let t be the total number of boxes.

t = 8 (number of stacks) + 4

Since we're told that 80 < t < 120, possible values of t are 84, 92, 100, 108 and 116. In other words, one of these values = t.

S1. t is a multiple of 9.
Of the 5 possible values listed, only 108 is a multiple of 9.
SUFFICIENT

S2. t is a multiple of 12.
If the number is divisible by both 3 and 4, then the number is divisible by 12.
Of the 5 possible values listed, both 84 and 108 are divisible by 3 and 4, therefore divisible by 12.
