Question 1
Tournament participants: Giselle, Gunjan, Tristan, Bennett
Given the following clues:
1. Giselle is younger than Gunjan
2. Gunjan is younger than Tristan
3. Tristan is younger than Bennett
4. Each person is exactly 3 years older than the person immediately younger than them.
5. Giselle is 15 years old.
Determine Tristan's age.
Step 1: From clues 1-3, the age order from youngest to oldest is:
Giselle → Gunjan → Tristan → Bennett
Step 2: From clue 4, each consecutive person differs by exactly 3 years.
So if youngest = x, then: Giselle=x, Gunjan=x+3, Tristan=x+6, Bennett=x+9
Step 3: From clue 5, Giselle (the 1st (youngest)) = 15
Therefore, x + 0 = 15
Solving: x = 15 - 0 = 15
Step 4: All ages are:
• Giselle = 15
• Gunjan = 18
• Tristan = 21
• Bennett = 24
Step 5: Tristan is the 3rd.
Therefore, Tristan = 21
Giselle → Gunjan → Tristan → Bennett
Step 2: From clue 4, each consecutive person differs by exactly 3 years.
So if youngest = x, then: Giselle=x, Gunjan=x+3, Tristan=x+6, Bennett=x+9
Step 3: From clue 5, Giselle (the 1st (youngest)) = 15
Therefore, x + 0 = 15
Solving: x = 15 - 0 = 15
Step 4: All ages are:
• Giselle = 15
• Gunjan = 18
• Tristan = 21
• Bennett = 24
Step 5: Tristan is the 3rd.
Therefore, Tristan = 21
