उत्तर
If x + y + z = 6 and z is an odd digit, then the three-digit number xyz is an odd multiple of 3.
Explanation:
We have, x + y + z = 6 and z is an odd digit.
Since, sum of the digits is divisible by 3, it will also be divisible by 2 and 3 but unit digit is odd, so it is divisible by 3 only.
Hence, the number is an odd multiple of 3.
