Explanation:

Correct option:4

Solution:

To determine if the number x468y05 is divisible by 11, use the divisibility rule: the difference between the sum of the digits in odd positions and the sum of the digits in even positions should be a multiple of 11.

Divisibility of 11 = (Sum of digits at odd places - Sum of digits at even places) = 0 or 11 =

(5 + y + 6 + x) - (0 + 8 + 4) = 1 1 = x + y + 11 - 12 = 11

=x+y= 11 + 1 ...

x + y = 12

Maximum value of (x + y) = 12
