- A3 : 5
- B3 : 2
- C2 : 5
- D5 : 3
Step-by-Step Solution
Matches played = 30 and matches won = 18, so won : played = 18 : 30 = 3 : 5. Repeating 3 : 2 is the trap — that is won : lost, a part-to-part ratio. Here the second quantity is the total, so the part-to-whole ratio 3 : 5 is needed. 2 : 5 is lost : played.
Answer: A) 3 : 5
