if the difference of sum of digits at odd 25861 is divisible by 11.

11 places and sum of digits at even places is As [(2 + 8 + 1) – (5 + 6) = (11 – 11)
0 or divisible by 11.
= 0

A number is divisible by 7, if the difference between twice the Subject Enrichment
ones digit of the given number and the remaining part of the given 383 6
number should be a multiple of 7 or it should be equal to 0.

For example: 3836 is divisible by 7. As 6 × 2 = 12
383 – 12 = 371
383 – 2 × 6 = 383 – 12 = 371 and 371 ÷ 7 = 53.
