8 U7 R1 Q$ ?5 N- i' U) {; M公仔箱論壇After seeing the IQ question 據說這是蘋果公司的面試題, it reminds me of grouping the left hand side numbers to reflect the number on the right.
3 {  h9 g1 U; X3 Twww2.tvboxnow.com* \: j6 L8 q% C7 ]
So the right hand side number 0 can be represented by number 1
9 q* ^' q* e( {" c0 D  H- [% {8 Qwww2.tvboxnow.comThe right hand side number 1 can be represented by 3,1,2,9,7,5公仔箱論壇; _6 j# C: X, r$ H6 h
The right hand side number 2 can be represented by 2,5,8,1,6,7,3,0公仔箱論壇/ h; k. D. D9 M% s' d
The right hand side number 3 can be represented by 5,9,8,3
# O& F' b. ?, K; ^6 _The right hand side number 4 can be represented by 6www2.tvboxnow.com" L6 w' ]/ o2 X' v8 p
Now the question is 8136, check the above list, 8,1,3,6 are grouped under 2. Therefore, the answer is 2公仔箱論壇' a: P  i. y* @7 M" N0 C5 o5 A

Sorry. My bad. Someone told me that it is actually counting the number of holes in the given number.
  L( `! H( l8 ytvb now,tvbnow,bttvbThere are 3 holes in 8136, two from number 8 and one from number 6 so the answer is 3.
