Write the largest digit in the blank space for 8_9484 so that the number formed is divisible by 11:
Answers
Answer:
Sum of odd digits = 8 + 9 + 8 = 25
Sum of even digits = blank space + 4 + 4 = blank space + 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.
