Question

what is the divisibility rule of 11?
explain with an example.​

Answer 1

HEY MATE HERE IS YOUR ANSWER...


For a test of divisibility by 11 start from the right and add every second digit. Now subtract from that total the sum of the remaining digits. The resulting number is divisibly by 11 if and only if the number you started with is divisible by 11.

For example consider 678234.

(4 + 2 + 7) - (3 + 8 + 6) = 13 - 17 = -4

which is not divisible by 11 so 678234 is not divisible by 11. Now try 908193

(3 + 1 + 0) - (9 + 8 + 9) = -22

which is divisible by 11 so 908193 is divisible by 11.

Answer 2

Divisibility rule of 11 -

let suppose you have a no - 1265

the even place digits are 2 and 5
........odd place............ are 1 and 6

now add even place digits =2+5 =7
........ add.... odd. place...... =1+6 =7

Now subtract then =7-7 =0
so it is divisible by 11

By subtraction of sum of even and odd no will be zero or any no. divisible by 11 then we can say that it is divisible by 11 .

In this case we have subtraction = 0
