What Is The Answers?

Lol.... this is a sometime I must share with you all.. If not share I feel sorry and bad of myself! 
saw this a very good maths quiz so I share in my facebook page let people guess what is the answer.
come out some people get it right but the answer they give got many version lah. Got people give 6, got some is R some even give the answer is way out of the space one! 
After that I give another quiz which is the next picture at below!
That one will be a little bit hard to get the right answer lah... not unless you are a 4x4 lover lah!
Actually the both question has linked to the car transmission. 
To see what is the answer just look at my last photo... that is my Hulkjero gear.
