A wheel that has 6 cogs is meshed with a larger wheel of 14 cogs. If the smaller wheel has made 35 revolutions, what will be the number of revolutions made by the larger wheel?	Answers:	A) 15	B) 12	C) 21	D) 9	E) 22
Explanation:   Let the number of revolutions made by the larger wheel be x   More cogs, less revolutions (Indirect proportion)   Hence we can write as   (cogs) 6 : 14 :: x : 35   â‡’6Ã—35=14 Ã— x   â‡’x = 15   15nswer: Option 15
