Answer 1

Answer:

Given numbers: 2651,2246,5324,6215

Divisibility rules of 11.

If the difference between the sum of digits in odd places from right to left of a number is a multiple of 11 or equal to zero, then the given number is divisible by 11

1. 2651

• sum of digits in odd places=

1+6 = 7

• sum of digits in even places=

5+2 = 7

Now, 2651 divisible by 11.

2. 2246

• sum of digits in odd places=

6+2 = 8

• sum of digits in even places=

4+2 = 6

Hence difference= 8-6 = 2

(2246 is not divisible by 11)

3. 5314

• sum of digits in odd places=

4+3 = 7

• sum of digits in even places=

5+1 = 7

Hence, 5314 is divisible by 11

4. 6215

• sum of digits in odd places=

5+2 = 7

• sum of digits in even places=

6+1 = 7

Hence, 6215 is divisible by 11

Therefore.....

Odd man

2246 is not divisible by 11.
