Solution

Let us consider the missing digit to be x.

We have, x27413÷11

Therefore the difference in the sum of digits at even places to the sum of digits at odd places should be 0 or divisible by 11

(x+7+1)-(2+4+3)=8+x-9=x-1

If we takex=1 then the difference will be 0

Hence the missing digit is 1
