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.tvb now,tvbnow,bttvb' v) H  L, m6 r. G9 F2 \% A
tvb now,tvbnow,bttvb  r: v# M( _0 |' w' m& p7 \
So the right hand side number 0 can be represented by number 1
4 j* s/ _3 w6 }8 o; atvb now,tvbnow,bttvbThe right hand side number 1 can be represented by 3,1,2,9,7,5
$ D! K/ K: W3 [( ], a" S/ E公仔箱論壇The right hand side number 2 can be represented by 2,5,8,1,6,7,3,0# B- u. |: ?2 v4 o6 \% F2 z' K
The right hand side number 3 can be represented by 5,9,8,3公仔箱論壇% {4 k$ r. [  j. x( p" P
The right hand side number 4 can be represented by 6公仔箱論壇- i& \9 _% ?5 x% E. v! a) B2 ?
Now the question is 8136, check the above list, 8,1,3,6 are grouped under 2. Therefore, the answer is 25.39.217.77:8898) G0 ?/ m5 g7 q& d; p% f( E4 k

Sorry. My bad. Someone told me that it is actually counting the number of holes in the given number.
. l1 e5 S, g; w7 ~, vThere are 3 holes in 8136, two from number 8 and one from number 6 so the answer is 3.
