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.
! e8 z" @# |6 H% t( U& j" G+ j
7 B% ?  C4 Y* P! o$ J+ C$ s9 Q公仔箱論壇So the right hand side number 0 can be represented by number 1
& f6 E$ S5 R5 p2 R1 \公仔箱論壇The right hand side number 1 can be represented by 3,1,2,9,7,5! d7 l* o) q2 S& f) y7 T1 Z
The right hand side number 2 can be represented by 2,5,8,1,6,7,3,0
7 z3 _8 B! A" B( a  y5.39.217.77:8898The right hand side number 3 can be represented by 5,9,8,3# P- G! c0 \2 l+ E
The right hand side number 4 can be represented by 62 i2 Q  A, W. R: I
Now the question is 8136, check the above list, 8,1,3,6 are grouped under 2. Therefore, the answer is 21 h' Q" B7 }3 `# ]

Sorry. My bad. Someone told me that it is actually counting the number of holes in the given number. . T' a! D+ r) ^, b9 W9 f& @; h
There are 3 holes in 8136, two from number 8 and one from number 6 so the answer is 3.
