Answer- The answer is 2

Answer 2

Answer:

2

Step-by-step explanation:

divisibilty by 11 = difference between the sum of the digits at odd and even place should be zero or 11

here 1+x+6=7+x

9+7+4=20

20-(7+x)= 11 ( cant take zero then x will be two digit and we want a ohe digit number)

solving this eqn we get x=2
