3 t4 r- G3 {: {- i4 y. ^tvb now,tvbnow,bttvbAfter 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.
  w% l! n. w. P* R! t2 i' I5 ?7 t公仔箱論壇& [! D* P: i5 F& c! p
So the right hand side number 0 can be represented by number 1
, i! ]: ^' l) Z! F$ ^5.39.217.77:8898The right hand side number 1 can be represented by 3,1,2,9,7,5
" S+ U0 j( L# u  itvb now,tvbnow,bttvbThe right hand side number 2 can be represented by 2,5,8,1,6,7,3,0
7 Q, H9 A  O+ l3 g2 {6 t- j4 RThe right hand side number 3 can be represented by 5,9,8,3* B  z8 L: J8 Y/ Z9 W
The right hand side number 4 can be represented by 6公仔箱論壇2 l5 s0 S4 m- q0 G1 N  p: ~8 t
Now the question is 8136, check the above list, 8,1,3,6 are grouped under 2. Therefore, the answer is 2

Sorry. My bad. Someone told me that it is actually counting the number of holes in the given number. % K$ [- [: b8 [7 f* p3 g; {
There are 3 holes in 8136, two from number 8 and one from number 6 so the answer is 3.
