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.

" Q" l$ X# h! ?/ b! w3 {公仔箱論壇So the right hand side number 0 can be represented by number 1
- u8 H/ X0 Q5 ~4 l$ k* Htvb now,tvbnow,bttvbThe right hand side number 1 can be represented by 3,1,2,9,7,5

3 l) e  F+ w5 H# stvb now,tvbnow,bttvbThe right hand side number 4 can be represented by 6公仔箱論壇' J) q- ]+ q' h( F, A+ m# Z* h
Now the question is 8136, check the above list, 8,1,3,6 are grouped under 2. Therefore, the answer is 2

Sorry. My bad. Someone told me that it is actually counting the number of holes in the given number. 公仔箱論壇) }& H  d& M& c; p. r
