A wheel that has 8 cogs is meshed with a larger wheel of 16 cogs. When the smaller wheel has made 24 revolutions, then the number of revolutions mad by the larger wheel is: Choose the correct choice from the following answers:  A) 10  B) 11  C) 15  D) 14  E) 12
E   12   Let the required number of revolutions made by larger wheel be x.   Then, More cogs, Less revolutions (Indirect Proportion)   16 : 8 :: 24 : x &lt;-&gt; 16 x x = 8 x 24   x = (8x 24)/16   x = 12
