Question 16

Explanation

Let's unravel this ticket distribution puzzle. We have 5 children (A, B, C, D, E) and 5 destinations. The main condition is that each city must be visited by exactly one child (one-to-one correspondence).

First, let's identify children with "exclusive" or unique choices:

1. Bali: Only appears in B's wish list. Thus, B must go to Bali.
2. Manado: Only appears in C's wish list. Thus, C must go to Manado.

Now we are left with 3 children (A, D, E) and 3 cities (Yogyakarta, Lombok, Padang).

• A wants: Yogyakarta or Lombok.
• D wants: Yogyakarta or Padang.
• E wants: Padang, Lombok, or Yogyakarta.

Based on the additional information in the question, we know that E goes to Lombok.

Since Lombok is taken by E, let's look at A's options:

• A originally wanted Yogyakarta or Lombok.
• The Lombok option is closed (since E is there).
• Therefore, the only remaining choice for A is Yogyakarta.

Thus, the father gives the Yogyakarta ticket to A. (As a completion, D will automatically get the ticket to Padang).
