Question 1148455
201/6 is just under 34, so there are 33 numbers that are multiples of 6
201/11 is just over 18, so there are 18 numbers that are multiples of 11
multiples of both at the same time are at 66 132 and 198, 3 numbers
Either or but not both include the sum of 34 and 18 minus 6 where it is both (2 numbers aren't counted for each of 66 132  198) or 45.
