प्रश्न
Write the smallest digit and the greatest digit in the blank space of the following number so that the number formed is divisible by 3:
4765 ______ 2
उत्तर
Based on the rules of checking divisibility, if the sum of the digits of a number is a multiple of 3, then that number is divisible by 3.
Therefore, by adding smallest digit 0, 476502 = 4 + 7 + 6 + 5 + 0 + 2 = 24
By adding the biggest digit 9, 476592 = 4 + 7 + 6 + 5 + 9 + 2 = 33
Both numbers will be divisible by 3.

If 24x is a multiple of 3, where x is a digit, what is the value of x?
(Since 24x is a multiple of 3, its sum of digits 6 + x is a multiple of 3; so 6 + x is one of these numbers: 0, 3, 6, 9, 12, 15, 18…. But since x is a digit, it can only be that 6 + x = 6 or 9 or 12 or 15. Therefore, x = 0 or 3 or 6 or 9. Thus, x can have any of four different values)
