Question

find the smallest and largest digits that can replace x. X represents a single digit 45272x is divisible by 8.​

Answer 1

Sum of the remaining digits=24

To make the number divisible by 3, the sum of its digits should be divisible by 3. As 24 is already divisible by 3, the smallest number that can be placed here is 0.

Now, 0+3=3

3+3=6

3+3+3=9

How ever, 3+3+3+3=12

If we put 9, then the sum of the digits will be 33 and as 33 is divisible by 3, the number will also be divisible by 3.

Therefore, the largest number is 9.
