A jar is filled with red, white, and blue tokens that are equivalent except for their color. The chance of randomly selecting a red token, replacing it, then randomly selecting a white token is the same as the chance of randomly selecting a blue token. If the number of tokens of every color is a multiple of 5, what is the smallest possible total number of tokens in the jar?  Choose the correct choice from the following answers.
A) 9  B) 12  C) 15  D) 18  E) 21
(Red / Total Coins)*(White / Total Coins) = (Blue / Total Coins)   i.e. Red*White = Blue*Total Coins   Let, Red = 3a   White = 3b   Blue = 3c   Total Coins = 3(a+b+c)   i.e. 3a * 3b = 3c*3(a+b+c)   i.e. a*b = c*(a+b+c)   For smallest values of a, b and c   2*3 = 1*(1+2+3)   i.e. Minimum Total Coins = 3*(1+2+3) = 12   Answer: Option 12
