Question

can anyone tell me the test of divisibility of 11​

Answer 1

Answer:

For a number divisible by 11.

let the number be 121 let another number be 132

1st digit =1 1st digit=1

2nd digit=2 2nd digit= 3

3rd digit=1 3rd digit =2

Then, then

(1st + 3rd)-2nd (1+2)-3

=(1+1)-2 =3-3

=2-2 =0

=0

If we get 0 or 11 at the last step then the number is divisible by 3.

Hope it helps!
