Answer 2

The value of *in the given question is 9 that is * = 9.

The complete division of 579*2 by 11 means that the number is completely divided by 11 leaving behind no remainder or remainder when number is divided by 11 should be 0.

This is only possible when 11 completely divides 579*2 and the divisor is a whole number.

So we have :--

Lets break number as 57/11 we get remainder as 2 which is carried over on 9.

So number now is 29 when 29/11 we get remainder as 7 now this is carried over on *.

We need to choose number in such a way when divided by 11 gives remainder as 2 as last digit of number is 2 so 22/11 gives complete division.

So when the number is 79/11 we get remainder as 2 .

Hence the value of * must be 9 for complete division of number by 11.

Hence number becomes as 57992 divide by 11 we have :--

57992/11 = 5272 remainder is 0.
