331, 482, 551, 263, 383, 242, 111
B
Correct answer
Explanation
All numbers except 383 are divisible by their digit sum. Checking: 331→3+3+1=7, and 331÷7=47.3. 482→4+8+2=14, and 482÷14=34.4. 551→5+5+1=11, and 551÷11=50.1. 263→2+6+3=11, and 263÷11=23.9. 242→2+4+2=8, and 242÷8=30.25. 111→1+1+1=3, and 111÷3=37. Only 383→3+8+3=14, and 383÷14=27.35 doesn't divide evenly.
