in each of the following problem a statement is given.If x represents a single digit,find the smallest digit and the greatest digit that can replace x. 12. 8x6250 is divisible by 3 13. 2746x6 is divisible by 4 14. 26412x is divisible by 6 15. 45272x is divisible by 8 please do it fast

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.
