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,bttvb9 [+ j5 ^/ Z% R5 M% {. T' ?% ~

/ V3 G# Q/ d+ `1 X- s; a# S# w公仔箱論壇So the right hand side number 0 can be represented by number 1
. w4 Z8 Y4 \2 n6 Q! H# d, K0 J/ r  ttvb now,tvbnow,bttvbThe right hand side number 1 can be represented by 3,1,2,9,7,5
$ E7 s  p1 M, N* B8 Ltvb now,tvbnow,bttvbThe right hand side number 2 can be represented by 2,5,8,1,6,7,3,0
9 l; W+ E9 i, a5 J! |  V5.39.217.77:8898The right hand side number 3 can be represented by 5,9,8,35.39.217.77:8898: W5 _! P: G" E7 _8 G9 I
The right hand side number 4 can be represented by 65.39.217.77:8898  J8 n+ ]4 G" S4 c/ S% w
Now the question is 8136, check the above list, 8,1,3,6 are grouped under 2. Therefore, the answer is 2& l( {3 N9 J( d& C2 B

1 s& s. |. q! K. R) D* wSorry. My bad. Someone told me that it is actually counting the number of holes in the given number. 公仔箱論壇3 {9 ?, x4 U/ P8 ~' {
There are 3 holes in 8136, two from number 8 and one from number 6 so the answer is 3.
