1~99 means 99 numbers
multiple of 2 means even number
99 - 49 even numbers = 50 odd numbers
among odd numbers, 17 multiples of 3, because 3*1, 3*3, ... 3*33 contain 17 numbers
50 - 17 =33, the answer.

I got the same answer with a different approach but I am not sure if it is by fluke, is this also correct:
I considered other prime numbers below 10 except 2 and 3 which is 5 and 7,
5 has: 100/5 = 20 multiples but 19 which are less than 100
7 has: 100/7 = 14.xx so around 14 multiples ,
total: 19+14=33 -- (D)
Would be great if someone can check Bunuel

Your solution doesn’t make sense. Why would adding the multiples of 5 and multiples of 7 give the count of numbers that are neither multiples of 2 nor multiples of 3?
