Question

10142 is divisible by 11​

Answer 1

A number is divisible by 11 if the difference of the sum of its digits in odd places and the sum of its digits in the even places is either 0 or a multiple of 11.

Here, Sum of odd places —

• = 0 + 4
• = 4

Here, Sum of Even places —

• = 1 + 1 + 2
• = 4

Now, difference between sum of its digits in odd places and the sum of its digits in the even places is—

• = 4 – 4
• = 0

Here, the difference of the sum of its digits in odd places and the sum of its digits in the even places is Zero.

Hence, 10142 is divisible by 11.
