5.39.217.77:8898" I# I# m/ R! g4 r
So the right hand side number 0 can be represented by number 1
6 G- N0 g+ E/ t2 L( O3 Mtvb now,tvbnow,bttvbThe right hand side number 1 can be represented by 3,1,2,9,7,5: u# @5 y- i- }) J' v
The right hand side number 2 can be represented by 2,5,8,1,6,7,3,0! k3 k9 J: ^8 u" n
The right hand side number 3 can be represented by 5,9,8,3
# J" C' b3 ?( W. U5.39.217.77:8898The right hand side number 4 can be represented by 6
* V% n( r5 i. |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. 5.39.217.77:8898+ J$ a2 ~1 ?# c  j$ L- v1 ]2 m
There are 3 holes in 8136, two from number 8 and one from number 6 so the answer is 3.tvb now,tvbnow,bttvb* T  Y) ~+ f. L9 {; K1 @
