We have reached the end of our contest. I would like to congratulate @doughtaker as the first person to provide all the correct answers. I believe this is @doughtaker's third contest win.
The answers to the questions are as follows:
- A
- 24, 54, 9
- Car = 2, Bus = 9, Train = 6
- 2
I will be posting the explanations in another post in a couple of days.
I would also like to thank all those that participated for their time and effort. I will have another contest in a few days time.
