Correct Answer:
Option B —
23
The problem gives us two major clues about the mystery number:
The sum of its digits is exactly five.
Three times that sum is eight less than the number itself.
Step-by-Step Logic:
Find the value of "three times the sum": We are told the sum of the digits is five. Three times that sum would be five, plus five, plus five, which gives us fifteen.
Find the mystery number: The problem states that this fifteen is "eight less than the number." This means the mystery number must be eight more than fifteen. Fifteen plus eight gives us twenty-three.
Double-check the choice: Does the number twenty-three match our first clue? The digits of twenty-three are two and three. Two plus three equals five. It matches perfectly!
