Correct Option (A)
The sum of all possible 3-digit numbers formed by distinct non-zero digits A, B, and C without repetition is denoted by x.
To determine the least value of x, the smallest distinct non-zero digits must be chosen for A, B, and C. These are 1, 2, and 3.
The 3-digit numbers that can be formed using 1, 2, and 3 without repetition are:
- 123
- 132
- 213
- 231
- 312
- 321
The sum x is calculated as: 123 + 132 + 213 + 231 + 312 + 321 = 1332.
Since 1332 is a 4-digit number, the least value of x is 1332. Therefore, Statement 1 is correct.
Incorrect Options:
Statement 2 claims that the 3-digit greatest value of x is 888.
As established in the explanation for Statement 1, the least possible value of x, formed using the smallest distinct non-zero digits (1, 2, 3), is 1332. Since 1332 is a 4-digit number, any other sum x formed by larger distinct non-zero digits will also be a 4-digit number or greater.
Consequently, x cannot be a 3-digit number. Therefore, Statement 2 is incorrect.
