If a/b = 4, b/c = 2/5, c/d = 6/5, d/e = 5/2 and e/f = 3, then what is the value of abc/def ?
Choose the correct choice from the following answers
A) 2704/4124
B) 4561/8645
C) 3235/7456
D) 475/8456
E) 3125/41472
Say a = 2. Then:   a/b = 4 --&gt; b = 1/2;   b/c = 2/5 --&gt; c = 5/4;   c/d = 6/5 --&gt; d = 25/24;   d/e = 5/2 --&gt; e = 5/12;   e/f = 3 --&gt; f = 5/36.   abc/def = (2*1/2*5/4)/(25/24*5/12*5/36) = 3125/41472.   Answer: 3125/41472.
