Answers
Q1. B
Q2. B
Q3. A
Q4. B
Reasoning
Q1 can't have A as its answer (otherwise it would contradict itself).
If Q1's answer was C (meaning Q4's answer was A), then Q3's answer would be C. However, Q2's answer should now be A, but this isn't allowed by Q1 (as Q4 is the first answer with A). This is a contradiction.
Therefore, Q1's answer is B (meaning Q3's answer is A).
For Q2's answer to be C, Q4's answer would have to be A, which would contradict Q4. Therefore, Q2's answer is B making Q4's answer B.

Puzzle 3
My local bus company has recently expanded and no longer has enough room inside its garage for all of its buses.
Twelve of their buses have to be stored outside.
If they decide to increase their garage space by 40% they will have enough room for all of their current buses, plus enough room to store another twelve in the future.
How many buses does the company currently own?

Hint
Think about the 40%, and how many buses that represents.
Answer
72 buses.
Reasoning
The garage is currently full, with 12 more buses outside.
If we increase the garage space by 40%, there will be enough space to house those 12 buses, plus 12 more in the future – a total of 24 buses.
This means that 40% of the current garage capacity is 24 buses.
Therefore, 10% of the current garage capacity is 6 buses.
Therefore, 100% of the current garage capacity is 60 buses.
So, the current garage holds 60 buses, and there are 12 more outside.
Therefore, we have a total of 72 buses.
Double-Checking
They currently have 72 buses, 12 of which are outside, so 60 are inside.
Increasing the garage space of 60 buses by 40% will give room for 60 x 1.4 = 84 buses.
Which is the 72 they currently own, with space for 12 more buses in the future.
This confirms the answer.

Hint
Start by imaging a sign saying 'BrainBashers Puzzles And Illusions'.
Answer
I commissioned an artist to paint a sign for BrainBashers that said 'BrainBashers Puzzles And Illusions', however, they made a terrible mistake.
The gaps between 'Puzzles' and 'And', and 'And' and 'Illusions' weren't the same, so the sign seemed oddly out of balance.
