Hi Everyone,

Spectrum Economics is holding its third solve the puzzles contest. This post contains 4 puzzles. The first person to solve all the puzzles wins 10 SBD. If we do not get a winner, the prize money of this contest will be added to the available winnings of the next contest.

How to Enter

To enter requires 1 upvote. Each entrant into the contest is allowed a maximum of 2 attempts. The attempt needs to be done in the comments section of the post. Some questions have several parts to them, all parts of each question need to be answered correctly for a chance to win.

I expect the answers to be presented in following format:

1. Answer 1a, 2b
2. Answer 2
3. Answer 3a, 3b, 3c
4. Answer 4

The closing date and time for the contest is 6PM USA Eastern Time 09/11/2017. Responses after this time will not be accepted. The answers will be provided in the comments section after the contest closes. The explanations for the answers will be provided in a separate post a few days after the contest closes.

The winner of the contest will be announced in the comments section and 10 SBD will be paid to the winner as soon as I receive the payout from the post. All attempts in the comments section will receive a 100% upvote regardless of answers provided. That’s right, I am also rewarding participation. Good luck everybody. The value of the upvote will depend upon my voting power at the time.
