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.
6 ?; r& \: n: d. L  ^
% t/ J& @: J* W% CSo the right hand side number 0 can be represented by number 1
# m' c7 Q7 \, {3 z; O8 q' t5.39.217.77:8898The right hand side number 1 can be represented by 3,1,2,9,7,5
9 a! W5 z! N# N  ^: r- Btvb now,tvbnow,bttvbThe right hand side number 2 can be represented by 2,5,8,1,6,7,3,0TVBNOW 含有熱門話題，最新最快電視，軟體，遊戲，電影，動漫及日常生活及興趣交流等資訊。. X" N4 E: S) w
The right hand side number 3 can be represented by 5,9,8,3
4 S( s2 k: h% u( t; ]3 Rtvb now,tvbnow,bttvbThe right hand side number 4 can be represented by 6+ A3 z+ `0 o' m2 i- X# k; z9 g) @# P
Now the question is 8136, check the above list, 8,1,3,6 are grouped under 2. Therefore, the answer is 2
