A circular rim A having a diameter of 24 inches is rotating at the rate of x inches/min. Another circular rim B with a diameter of 32 inches is rotating at the rate of y inches/min. What is the value of y in terms of x, if both the rims reach their starting positions at the same time after every rotation.  Options
A) 3x/4	B) 4x/5	C) 7x/5	D) 5x/7	E) 4x/3
t = S1/V1 = S2/V2   or, 24/x = 32/y   or, y = 24x/32 = 3x/4 (3x/4nswer 3x/4)
