Answer

To determine the minimum number of tickets Martin's family has purchased for the picnic, we will analyze the family structure based on the information provided in the question.

### Step-by-step Solution:

1. **Identify Family Members**:
- Martin (the eldest son)
- Martin's sister
- Two additional children (since there are three children in total)
- One grandfather
- One grandmother
- Two fathers (Martin's father and his grandfather)
- Two mothers (Martin's mother and his grandmother)
- One daughter-in-law (Martin's mother)
- One father-in-law (Martin's grandfather)
- One mother-in-law (Martin's grandmother)

2. **Count Unique Individuals**:
- **Children**: Martin, his sister, and one more child (3 children total)
- **Grandparents**: 1 grandfather and 1 grandmother (2 grandparents total)
- **Parents**: Martin's father and mother (2 parents total)
- **In-laws**: The grandparents are also the in-laws to Martin's parents, but they do not add to the count since they are already included.

3. **Summarize the Count**:
- Martin (1)
- Martin's sister (1)
- One more child (1)
- Martin's father (1)
- Martin's mother (1)
- Martin's grandfather (1)
- Martin's grandmother (1)

4. **Total Count**:
- Total family members = 1 (Martin) + 1 (sister) + 1 (additional child) + 1 (father) + 1 (mother) + 1 (grandfather) + 1 (grandmother) = 7

5. **Conclusion**:
- Therefore, the minimum number of tickets purchased for the entire family is **7**.
