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.( T; i& T% q3 J2 ?* {, q, y- a

  c" S; s8 s1 \2 P' ^7 [3 z) r3 ~. r& nSo the right hand side number 0 can be represented by number 1 tvb now,tvbnow,bttvb: P4 y6 D! J. m) m5 R3 r$ `- C
The right hand side number 1 can be represented by 3,1,2,9,7,5tvb now,tvbnow,bttvb  ^% Q1 C; L1 h3 d4 X
The right hand side number 2 can be represented by 2,5,8,1,6,7,3,0
3 Y# s9 z$ O1 r: x. _www2.tvboxnow.comThe right hand side number 3 can be represented by 5,9,8,35 U2 i5 U  D3 r; c$ M
The right hand side number 4 can be represented by 65 A/ Z5 g: Z" k" }1 Q, \2 R
Now the question is 8136, check the above list, 8,1,3,6 are grouped under 2. Therefore, the answer is 2

There are 3 holes in 8136, two from number 8 and one from number 6 so the answer is 3.
