• total ways to park the cars having same colour =5!
  
  but according to question ,there are 3 red cars,so no. of ways for parking
  3 red cars=3!
  and both blue & green in 1 ways
  
  so, 5!/1!*3!*1! = 20 ways
  
  hence correct answer must be 20 ways.

• Ans: 9 days
  
  Explain:-
  ........let d is the number of the day
  12*18 = 12*6 +16*d
  16*d = (12 *18 - 12*6) = 12*12
  d = 144/16 = 9
