- t8 g; ]  m  W  `" m2 H0 [% L. BAfter 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.  P! [- e6 T$ K0 F% ^+ c
! Q0 h% I" P1 D: o4 [/ z
So the right hand side number 0 can be represented by number 1 ) d% t, Z8 _$ o$ d
The right hand side number 1 can be represented by 3,1,2,9,7,5
* c5 e( V0 Y( o3 r2 Y: P) uThe right hand side number 2 can be represented by 2,5,8,1,6,7,3,0  p+ ?1 h2 r1 m, a$ r2 l
The right hand side number 3 can be represented by 5,9,8,3
7 C; Y  B$ \' h+ j9 r5 V) B5.39.217.77:8898The right hand side number 4 can be represented by 6
: `3 ~  b( X. {8 J% [3 a5.39.217.77:8898Now the question is 8136, check the above list, 8,1,3,6 are grouped under 2. Therefore, the answer is 2
& C9 u3 C4 \6 ?5 R7 A
7 s  z( j# e( ztvb now,tvbnow,bttvbSorry. My bad. Someone told me that it is actually counting the number of holes in the given number. 3 B- a2 _8 e+ N5 k- y+ @
There are 3 holes in 8136, two from number 8 and one from number 6 so the answer is 3.
