Question

Which of the following numbers is divisible by 11?

• A. 10000001, 459756
• B. 9000001,45975
• C. 4569874, 547952
• D. 4568947, 97455

Answer 1

The correct option is A

10000001, 459756

To check the divisibility of a number by 11, we find the difference between the sum of the digits at the odd places (from the right) and the sum of the digits a the even places (from the right) of the number. If the difference is 0 or divisible by 11, then the number is divisible by 11.
For 62678

Sum of digits at odd places = 8 + 6 +6 = 20

Sum of digits at even places = 2 + 7 = 9

difference = 20 - 9 = 11

Hence, 62678 is divisible by 11
You can check that the othe rnumbers are not divisible by 11
