Question

Which digit should be filled in the blank space so that the number 618_9 is divisible by 11?

Answer 1

Answer:61809

Step-by-step explanation:

618x9

because divisibility of 11 is to be find by subtract the sum of even digit from sum of odd digit that is equal to zero or divide by 11

618x9

so sum of odd digit is6+8+9 =23 and sum of even digit 1+x

now their difference 23-(1+x) =  0 or divide by 11

23-1-x = 22-x

if we put x = 0 the ans 22 that is divide by 11

so 61809 is divisible by 11
