The next one describe the "11" as there are two "1", therefore 21

/ g( t7 H" G; k: V0 t1 E5.39.217.77:8898After 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.
$ m) D! V, }0 B! X6 c. atvb now,tvbnow,bttvb5.39.217.77:8898* E  O/ e1 G& \* m- _
So the right hand side number 0 can be represented by number 1
5 [) v. e: ^8 Vtvb now,tvbnow,bttvbThe right hand side number 1 can be represented by 3,1,2,9,7,5
( g0 ^' N6 I- y& I3 i/ s- v: J8 K+ S5.39.217.77:8898The right hand side number 2 can be represented by 2,5,8,1,6,7,3,0" ]. F% N" p+ F; f) z. A
The right hand side number 3 can be represented by 5,9,8,3公仔箱論壇# z4 U3 t: P5 N! Y% l7 A
The right hand side number 4 can be represented by 6
( V; e( |0 i5 ^. N5.39.217.77:8898Now the question is 8136, check the above list, 8,1,3,6 are grouped under 2. Therefore, the answer is 2

Sorry. My bad. Someone told me that it is actually counting the number of holes in the given number.
% J- L+ }' S- D: y: u5.39.217.77:8898There are 3 holes in 8136, two from number 8 and one from number 6 so the answer is 3.TVBNOW 含有熱門話題,最新最快電視,軟體,遊戲,電影,動漫及日常生活及興趣交流等資訊。# ?: t  a. f( g# N1 j
