Question

List value to be given to *so that the number 5*
3457 is divisible by 11 is

Answer 1

Answer:

523457

Step-by-step explanation:

5*3457

A number is divisible by 11, if the difference between the sum of odd-numbered digits and the sum of even-numbered digits is a multiple of 11.

i.e. if (5 + 3 + 5) - (* + 4 + 7) is divisible by 11

13 - * + 11  is divisible by 11

24 - *  is divisible by 11

If we subtract 2 from 24, we get 22 which  is divisible by 11.

So we should replace * with 2, to make 5*3457 is divisible by 11.

So, the number is 523457  .
