Any 6-digit number formed by repeating 3 digits like 656656 or 486486

1.	Any 6-digit number formed by repeating 3 digits like 656656 or 486486 is always divisible by: 1. 62. 113. 94. 3
Answer» Correct Answer - Option 2 : 11 Concept used: If the difference of the alternating sum of the digits of a number is a multiple of 11, then the number is divisible by 11 Calculation: Checking above given digits 656656 or 486486 Adding digits alternately then we got (6 + 6 + 5) and (5 + 6 + 6) The difference between the number is 0 which is multiple of 11 Checking other given number Adding digits alternately then we got (4 + 6 + 8) and (8 + 4 + 6) The difference between the number is 0 which is divisible by 11 ∴ The above pattern of the number is always divisible by 11

Answer» Correct Answer - Option 2 : 11

Concept used:

If the difference of the alternating sum of the digits of a number is a multiple of 11, then the number is divisible by 11

Calculation:

Checking above given digits 656656 or 486486

Adding digits alternately then we got (6 + 6 + 5) and (5 + 6 + 6)

The difference between the number is 0 which is multiple of 11

Checking other given number

Adding digits alternately then we got (4 + 6 + 8) and (8 + 4 + 6)

The difference between the number is 0 which is divisible by 11

∴ The above pattern of the number is always divisible by 11
