Number options: 134564, 284961, 692481, 924682
Formula used:
A number is divisible by 11 if the difference between the sum of the digits in the odd positions and the sum of the digits in the even positions is a multiple of 11.
Calculation:
For 134564:
Odd positions: 1 + 4 + 6 = 11
Even positions: 3 + 5 + 4 = 12
⇒ Difference: |11 - 12| = 1
Not divisible by 11
For 284961:
Odd positions: 2 + 4 + 6 = 12
Even positions: 8 + 9 + 1 = 18
⇒ Difference: |12 - 18| = 6
Not divisible by 11
For 692481:
Odd positions: 6 + 2 + 8 = 16
Even positions: 9 + 4 + 1 = 14
⇒ Difference: |16 - 14| = 2
Not divisible by 11
For 924682:
Odd positions: 9 + 4 + 8 = 21
Even positions: 2 + 6 + 2 = 10
⇒ Difference: |21 - 10| = 11
Divisible by 11
∴ The correct answer is option (4).
