Question

8876=5
7710=1
0349=2
3009=3
3296=2
8371=x
Find X

Answer 1

x for the last one is 2

reason-

in the number "8876" there are 2 circles in the first "8" and 2 circles in the second "8" and also there's one circle in the "6",in total 5 circles.
so that means the number 5 represents the number of circles in the number

subsequently the number "7710" has only one circle since "0" in it is a closed structure therefore "7710= 1".

using this logic we can deduce that the number "8371" has a "8" with 2 circles in it.therefore,x=2.

hope it helps...
