Answer:

16

Step-by-step explanation:

There are 9 that are divisible by 11 (11, 22, 33, ..., 99 = 9 × 11)

There are 7 that are divisible by 13 (13, 26, 39, ..., 91 = 7 × 13)

There aren't any numbers common to both of these lists, so there aren't any numbers between 1 and 100 divisible by both 11 and 13

So there are 9 + 7 = 16 numbers divisible by either 11 or 13 but not both.
