Worked Solution
Step 1: Find the Arts and Crafts percentage.
All five percentages must add to 100%.
Arts and Crafts = 100% - 15% - 30% - 25% - 20% = 10%
Step 2: Find which activity equals exactly 3 x Arts and Crafts.
3 x 10% = 30%
Step 3: Identify the activity with 30%.
Sports = 30%
Verify: 30% / 10% = 3
Answer: Sports
Correct answer: Sports
