(A) 70% (B) 71% (C) 72% (D) 73% (E) 74%
Natural Numbers are counting numbers 1,2,3,4,5,...,infinity.
every other number is divisible by 2, so numbers that are divisible by 2 is 50%,
that leaves 50%
every 3rd number is divisible by 3
1/3 * 50% = 16 2/3 % , total so far 66 2/3 % , leaving 33 1/3 % left
every 5th number is divisible by 5
1/5 * 33 1/3 % = 6 2/3 %, total so far 73 1/3 % , leaving 26 2/3 % left
so by the way I figure it, and if anyone finds I am mistaken please let me know, the
answer is D. 73%
