Solution

The below table shows the matching of families in each round as per the given conditions.

First, we will trace the matches of 57 to find who he will replace in the final round [1 or 9].

Round 1: 8, Round 2: 25, Round 3: 7, Round 4: 5, Round 5: 1, Round 6: 9.

Thus, 57 will take the place of 1 in round 6.

Thus, we will have to check which family among the options take the place of 9.

  1. 35

Let’s trace the matches of 35 in all the rounds.

Round 1: 30, Round 2: 3, Round 3: 4, Round 4: 3, Round 5: 1, Round 6: 9.

Thus, 35 will also take the place of 1 round 6. Therefore, it cannot be the answer.

Similarly, we can find that 39 and 58 also take the place of 1 in round 6. Thus, they are also ruled out.

2. 47

Round 1: 18, Round 2: 16, Round 3: 15, Round 4: 13, Round 5: 9, Round 6: 1

Thus, 47 will take the place of 9 in the sixth round.

Hence, the answer is option B.
