One hundred multiples of seven are chosen at random, and 200 multiples of eight are chosen at random. Approximately what percentage of the 300 selected numbers are odd?	Choose the correct choice from the following choices:  A) 34.33%  B) 16.67%  C) 35.33%  D) 36.33%  E) 37.33%
--&gt; Multiples of 7 are 7, 14, 21, 28, 35, 42....   Out of first 4 multiples, 2 are odd; out of first 6 multiples, 3 are odd.   So approx. 50 % of the 100 multiples are odd i.e 50 multiples.   --&gt; Similalrly, for 8 multiples are:8,16,24...   All are even so 0 % are odd.   Total odd= (50+0)/(100+200)= 50/300=(1/6) = 16.67%   Answer 16.67%
