Hey friend
Divisibility rule for 11 = diffrence between sum of even and odd place number should be zero or divisible by 11.
Even place sum = 6+2+x+2+3 = 13+x
Odd place sum = 3+4+1+1+1 = 10
Diffrence = 13+x -10 = 3+x
Here x is a single digit non negetive number ... X+3 = 11
X = 8
Hope it will help you !!
