If a*b*c=130, b*c*d = 65, c*d*e=750 and d*e*f=250 the (a*f)/(c*d) = ? Choose the correct choice from the following options: A) 1/2 B) 2/3 C) 3/4 D) 4/3 E) None of these
Explanation :   aâˆ—bâˆ—c/bâˆ—câˆ—d= 130/65 =&gt; a/d = 2   dâˆ—eâˆ—f/câˆ—dâˆ—e= 250/750 =&gt; f/c = 1/3   a/d* f/c = 2 * 1/3 = 2/3   Answer : 2/3
