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.

7 e. {- |" X8 }, r7 M' z4 uTVBNOW 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。So the right hand side number 0 can be represented by number 1 5.39.217.770 M3 D1 d* ^, ^0 y; X- d8 X
The right hand side number 1 can be represented by 3,1,2,9,7,5
+ K  X4 W( U- r5.39.217.77The right hand side number 2 can be represented by 2,5,8,1,6,7,3,0

The right hand side number 4 can be represented by 6
! `% t( p  ]8 k1 c- d5 Y  Y0 ZNow the question is 8136, check the above list, 8,1,3,6 are grouped under 2. Therefore, the answer is 25 O2 t# Z$ c1 ^9 b% k( Z8 C6 L  _

Sorry. My bad. Someone told me that it is actually counting the number of holes in the given number. % s1 F! r8 |  y% l
There are 3 holes in 8136, two from number 8 and one from number 6 so the answer is 3.
