Answer:
0 numbers
Explanation:
The number of factors of a number is given by the formula:

where a is the highest power of 2 that divides the number and b is the highest power of 3 that divides the number.
We want a number less than 100 with exactly 11 factors.
So, we want.

We can factor 11 as 1*11. So, we need a + 1 = 1 and b + 1 = 11.
Solving for a and b, we get a = 0 and b = 10.
However, there are no numbers less than 100 that are divisible by 10 only. The smallest number divisible by 10 is 10.
Therefore, there are 0 numbers less than 100 with exactly 11 factors.
