45 multiples of 2 plus 30 multiples of 3 minus 15 multiples of 6 equals 60 numbers
60 numbers
150. 100/ 6 = 16 2/3 so 17 x 6 = 102 is the first three digit multiple of 6 1000 / 6 = 166 2/3 so 166 x 6 = 996 is the last three digit multiple of 6 So there are 166 - 17 + 1 = 150 three digit multiples of 6.
They are the multiples of 6.
95, is the two digits after the last digit of the multiple of 5's.
Multiple of both 2 and 3 <=> multiple of 6 So require 2 digit multiples of 6. 2*6 = 12 and 16*6=96 So the answer is 16-2+1 = 15
45 multiples of 2 plus 30 multiples of 3 minus 15 multiples of 6 equals 60 numbers
