Explanation:

To determine if a number is divisible by 11, subtract the sum of the digits in even positions from the sum of the digits in odd positions. The result must be zero or a multiple of 11.

- Number: 925x85

- Odd place digits: 9, 5, 8

- Even place digits: 2, x, 5

Calculate:

- Odd sum = 9 + 5 + 8 = 22

- Even sum = 2 + x + 5 = 7 + x

For divisibility by 11:

- |22 - (7 + x)| should be 0 or a multiple of 11

- Simplify: 22 - 7 - x = 15 - x

- 15 - x = 11 gives x = 4

Correct Answer:

- Option 4: 4
