Answer
Answer: C
Step-by-step explanation:
The numbers we are looking for have the formula 15n+1 < 100, where n is a positive integer.
Putting n=1,
15×1+1=16
Putting n=2,
15×2+1=31
Putting n=3,
15×3+1=46
Putting n=4,
15×4+1=61
Putting n=5,
15×5+1=76
Putting n=6,
15×6+1=91
Putting n=7,
15×2+1=106
But 106 > 100, so it's not possible.
Therefore, there are 6 possible numbers.

There is also integer 1 which leaves remainder 1, so answer is D(7)
