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.
3 {0 t# K% X( I  {9 r8 C: ~6 U5.39.217.761 g  l4 y: C0 w9 o/ m- p* o3 Y
So the right hand side number 0 can be represented by number 1 3 c; k2 s0 @. e( q
The right hand side number 1 can be represented by 3,1,2,9,7,5
- l7 Z. D, K  }, ~The right hand side number 2 can be represented by 2,5,8,1,6,7,3,0* a2 n# V+ R; p9 X1 u! D: H
The right hand side number 3 can be represented by 5,9,8,3
3 p. {$ h* z% [9 ~7 \The right hand side number 4 can be represented by 6
0 x( Y0 w% c. H6 |- ^) i7 eNow the question is 8136, check the above list, 8,1,3,6 are grouped under 2. Therefore, the answer is 2

  }- T# M  r* ^/ }$ w# h& K9 ^/ WSorry. My bad. Someone told me that it is actually counting the number of holes in the given number. / {# [3 S$ @& A; C8 e
There are 3 holes in 8136, two from number 8 and one from number 6 so the answer is 3.
