Answer 2

Given data: 2589*1

To find: The value of *

Solution:

• According to the rule, The difference between sum of odd place value to the sum of even place value. It should be either 0 or divisible by 11.
• The given number is 2589*1 in this the even place values are added ( 2 + 8 + * = 10 + *).
• The odd place values are added (5 + 9 + 1 = 15).
• The sum of odd place is 15 and the even place is 10 + *. Here the given number is completely divisible by 11.
• If we give the value of * is 5 then we get 15 - 15 = 0.
