Question

which one of the following numbers is exactly divisible by 11 following no. a) 235641 b) 245642 c) 315624 d) 415624 e) none of these​

Answer 1

my answer is D) 415624

4-1=3

3+5=8

8-6=2

2+2=4

4-4=0

0 is divisible by 11

Answer 2

Answer:

The correct answer is Option D : $415624$

Step-by-step explanation:

Check the number from left to right and add the alternating sum of the digits. If it is divisible by $11$, then the initial figure is divisible by $11$ as well.

For instance, in our answer $415624$, find the alternating sum of the digits.

$4-1+5-6+2-4=0$

$\frac{0}{11}=0$

Hence, we can say that $415624$ is divisible by $11$.

Hence the answer is Option D.
