➡➡➡➡So first we have to KNOW the divisibility test of 11.

➡➡If the alternate numbers from right to left are ADDED as in the above number

 we will add 1+2+(no.we have to find=x)

                    3+x

➡➡And other alternate numbers as 7+3+4=14

So the rule is that when you SUBTRACT the first list of alternate numbers from the second list, the difference should be 0 or a multiple of 11.

➡➡So 3+x-14=0[As we have to find the smallest number]

     3+x=14

     x=14-3 

     x=11

➡➡Because the number is EQUAL by 11 we will subtract 11 from the number.

२1➡➡1-11=0

Therefore the smallest number is 0.
