Question

Is 253101 is divisible by 11 give reasons

Answer 1

Answer:

No

Step-by-step explanation:

Here an easy way to test for divisibility by 11. Take the alternating sum of the digits in the number, read from left to right. ... So, for instance, 2728 has alternating sum of digits 2 – 7 + 2 – 8 = -11. Since -11 is divisible by 11, so is 2728.

For your question:

2 - 5 + 3 - 1 + 0 - 1 = -2

-2 is not divisible by 11. So, 253101 is not divisible by 11.

Answer 2

Answer:

By divisibility rule :-

253101

2+3+0=5

5+1+1=7

5+7=12

No,it is not divisible by 11 because it's divisibility rule says that last sum should be divisible by 11.

But in this question sum is 12 and 12 is not divisible by 11....

Hence 253101 is not divisible by 11....
