Question

Which difit should be written in the place of*,sobthat 56*891will be divisible by 11?

Answer 1

Answer: 1

Step-by-step explanation:

For a number to be divisible by 11, the difference of the sum of alternate digits will be 0 or a multiple of 11

Let m be the missing number

Then the sum of alternate digits are

1+8+6=15

and 9+m+5=14+m

So thie difference is 15-(14+m)=1-m will be 0 or multiple of 11

So possible value for m here is 1

So the missing digit will be 1 so that 561891/11=51081
