Question

which of the following number is divisible 11 a) 97106 b)570825 c)109625 d) 82093​

Answer 1

Answer:

We know the divisibility rule for 11:

If the difference of the sum of its digits at odd places and sum of its digits at even places is either 0 or a number divisible by 11.

2871:

Sum of the odd places =2+7=9

Sum of the even places =8+1=9

Difference = Sum of the odd places − Sum of the even places

Difference =9−9=0

So, 2871 is divisible by 11.

So, option C is correct.
