Question

Write a digit in the blank space so that the number will be divisible by 11...
= 8 _ 9484

Answer 1

odd places = 8+9+8=25.

even place = 4+4=8.

difference= 25-8=17.

fill answer is 17.

Answer 2

Answer:

Step-by-step explanation:

If the number of digits is even, add the first and subtract the last digit from the rest. The result must be divisible by 11. If the number of digits is odd, subtract the first and last digit from the rest. The result must be divisible by 11.

So,

Sum of odd digits = 8 + 9 + 8  = 25

Sum of even digits = 4 + 4 = 8

The number is divisible by 11 if the difference between the sum of the digits at odd places and the sum of the digits at even places is divisible by 11.

If we make the sum of even digits = 14 then we will have difference = 25 - 14 = 11 which is divisible by 11.

To make the sum of even digits = 14,

the number at black space would be 6.
