200 hundred multiples of seven are chosen at random, and 500 multiples of eight are chosen at random. Approximately what percentage of the 700 selected numbers are odd?
Choose the correct choice:  A) 14.29%  B) 15.29%  C) 16.29%  D) 17.29%  E) 18.29%
--&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 200 multiples are odd i.e 100 multiples.   --&gt; Similalrly, for 8 multiples are:8,16,24...   All are even so 0 % are odd.   Total odd= (100+0)/(200+500)= 100/700=1/7 = 14.29%   14.29%nswer 14.29%
