1. Calculate the age for each Santa by performing the multiplication:
- Santa 'A': 12.2 x 5 = 61 years
- Santa 'B': 5.625 x 9.6 = 54 years
- Santa 'C': 16.8 x 5 = 84 years
- Santa 'D': 12.5 x 5.2 = 65 years
2. Convert height from inches to feet to check Clue 1 (taller than 5 feet = taller than 60 inches):
- Santa 'A': 63 inches > 60 inches (Meets)
- Santa 'B': 72 inches > 60 inches (Meets)
- Santa 'C': 55 inches < 60 inches (Fails)
- Santa 'D': 67 inches > 60 inches (Meets)
3. Convert weight from ounces to pounds to check Clue 2 (more than 205 pounds). Since 1 pound = 16 ounces, divide the ounce value by 16:
- Santa 'A': 3,168 oz / 16 = 198 pounds < 205 pounds (Fails)
- Santa 'B': 3,281 oz / 16 = 205.0625 pounds > 205 pounds (Meets)
- Santa 'C': 3,312 oz / 16 = 207 pounds > 205 pounds (Meets)
- Santa 'D': 3,342 oz / 16 = 208.875 pounds > 205 pounds (Meets)
4. Check Clue 3 (older than 57 years old) using the calculated ages:
- Santa 'A': 61 > 57 (Meets)
- Santa 'B': 54 < 57 (Fails)
- Santa 'C': 84 > 57 (Meets)
- Santa 'D': 65 > 57 (Meets)
5. Determine which Santa meets all three clues:
- Santa 'A': Meets Clue 1 and Clue 3, but fails Clue 2.
- Santa 'B': Meets Clue 1 and Clue 2, but fails Clue 3.
- Santa 'C': Meets Clue 2 and Clue 3, but fails Clue 1.
- Santa 'D': Meets Clue 1 (67>60), Clue 2 (208.875>205), and Clue 3 (65>57).
Santa 'D' is the real Santa.
