Answer:
8
Step-by-step explanation:
the divisibility rule of 11 is that that difference of the numbers at even places and that of of odd places must be zero or a multuple of 11.
That means, (1 + m + 4 + 5) - (0 + 6 + 1) must be a multiple of 11
10 + m - 7
3 + m
3+m = 11 ( m can't be bigger than 10)
m =8
