Hey dear here is your answer!!!!!

⭕To check the divisibility test for 11 we take alternate no. and add it... For example

Let's talk no. 54678

❌ Now take alternate digit and add them

5+6+8-(4+7)
19-11
8
8 isn't divisible by 11 so 54678 isn't divisible by 11

⭕ Now let's come back to question !

❌67x19

6+x + 9-(7+1)
15+x-8
7+x

❌X should be 4 to get divisible by 11 therefore
the least possible value of x is 4

hey here is ur answer

to check whether a number is divisible by 11 or not we use the following method

sum of odds=sum of even numbers or the difference between them must be a factor of 11

so we shall check it

7+1=8, 6+9=15

15-8=7

it is not divisible

let the sum of 6,9,x be y

y - 8=11

11+8=19

19-15=4

x=4

I hope this helps you
