​

Answer 1

Step-by-step explanation:

$it \: can \: be = 2 \: or \: 5 \: or \: 8$

Answer 2

Answer:

$\huge{\boxed{\rm{\red{x=2}}}}$

Step-by-step explanation:

Given that:-

61x6

If it is divisible by 3 then it follows the divisiblity by 3

The sum of all digits is divisible by 3then the number is divisible by 3

Sum of the digits=6+1+x+6=13+x

The multiple of 3 after 13 is 15

so 13+x=15

=>x=15-13

=>2

The value of X=2

so the resultant number=6126

sum of the digits =6+1+2+6=15

it is divisible by 3
