Answer 2

Step-by-step explanation:

For A Number to be divisible by 3 the sum of the digits should be divisible by 3.

So 6+2+2+1+5+x+5 should be divisible by 3

or 21 +x should be divisible by 3.

So x can be 0, 3, 6, 9,

For A Number to be divisible by 11 the sum of digits of odd numbers subtracted by the sum of digits of even numbers should be divisible by 11

6+2+5+5-2-1-x should be divisible by 11

or 15-x should be divisible by 11

So x can be 4
