Let's solve each brain teaser step by step:
---
1. Move 1 match to make this sum correct
Image:
```
6 + 4 = 4
```
Solution:
The equation `6 + 4 = 4` is incorrect. To make it correct, we need to move one matchstick.
- Take the top left matchstick from the `6` and place it vertically on the right side of the `6`. This changes the `6` into a `5`.
- The equation now becomes:
```
5 + 4 = 9
```
Final Answer:
Move one matchstick to change `6` into `5`, making the equation `5 + 4 = 9`.

2. Which word is the odd one out?
Words:
```
Snug
Dam
Pans
Keep
Live
Grid
Trap
Rats
```
Solution:
To determine the odd one out, look for a pattern or category that fits most of the words but excludes one.
- All the words except "Grid" are related to animals or their behavior:
-
Snug: A type of fish.
-
Dam: Refers to beavers building dams.
-
Pans: Refers to panthers.
-
Keep: Refers to keeping animals (e.g., in a zoo).
-
Live: Refers to living creatures.
-
Trap: Refers to trapping animals.
-
Rats: Refers to rodents.
-
Grid does not fit this animal-related theme.
Final Answer:
The odd one out is
Grid.

3. What is the missing number?
Sequence:
```
8735?
```
Solution:
This sequence appears to be based on a pattern involving the digits. Let's analyze the digits:
- The sequence is `8, 7, 3, 5, ?`.
- Notice that the digits are decreasing in value when read backward:
- `5` → `3` → `7` → `8`.
- The pattern seems to involve subtracting specific values:
- `8 - 1 = 7`
- `7 - 4 = 3`
- `3 + 2 = 5`
- Following this alternating addition/subtraction pattern, the next step would be to subtract `1` from `5`.
Thus, the missing number is `4`.
Final Answer:
The missing number is
4.

4. How many holes does this t-shirt have?
Image:
A t-shirt with several bullet holes.
Solution:
Count all the visible holes in the t-shirt:
- There are
7 bullet holes in the shirt.
- Additionally, every t-shirt has
2 inherent holes for the arms and
1 hole for the head.
So, the total number of holes is:
- Bullet holes: 7
- Arm holes: 2
- Head hole: 1
Total: \( 7 + 2 + 1 = 10 \)
Final Answer:
The t-shirt has
10 holes.

5. If John’s son is my son’s father, who am I?
Question:
"If John’s son is my son’s father, who am I?"
Solution:
Let's break this down logically:
- John’s son is mentioned as "my son’s father."
- Since my son’s father is me, it means John’s son is me.
Therefore, you are
John’s son.
Final Answer:
You are
John’s son.

6. What is wrong with this room?
Image:
A room with a clock, curtains, a table, a chair, a trash can, and books.
Solution:
Look for something unusual or inconsistent in the room:
- The clock shows
10:10, which is fine.
- The curtains are open, letting in light.
- The table has a lamp, chair, and books, which is normal.
- However, the
trash can is empty, even though there are crumpled papers on the floor near it. This suggests someone should have thrown the papers away.
Final Answer:
The trash can is empty while there are crumpled papers on the floor.

Final Answers for All Questions:
1. Move one matchstick to change `6` into `5`, making the equation `5 + 4 = 9`.
2. The odd one out is
Grid.
3. The missing number is
4.
4. The t-shirt has
10 holes.
5. You are
John’s son.
6. The trash can is empty while there are crumpled papers on the floor.
Boxed Final Answer:
\[
\boxed{5 + 4 = 9, \text{Grid}, 4, 10, \text{John's son}, \text{Trash can is empty}}
\]
