1. The answer is 87. Just turn the picture upside-down in your head.
2. The answer is 2581 = 2. Try to count the number of circles in each 4-digit number. For example, 6 has one circle, 8 has 2 of them, and 6889 has 6! Got it?
3. Answer: D = 1345; E = 2440.
   The bottom numbers are connected to the upper level. First, add the numbers in the bottom line: 198 + 263 = 461.
   Now you see that the number you got is greater than its neighbour above: 461 > 446.
   Subtract these numbers: 461 – 446 = 15.
   If you check the rest of the pyramid, you’ll get 15 in each case.
   Ta-da! Here’s the key.
4. The answer is diagram B. It’s just some simple math:
   How many caramel candies are there in the box? 30 – 10 = 20.
   And how many coconut candies are there? 25 – 10 = 15.
   Now you can find out how many plain chocolate candies were in the box! 50 – (20 + 15 +10) = 5.
5. The bus is moving to the left because the door is on the other side.
6. To solve this, you’ll need to imagine the number 29 in Roman digits. That way, it’ll look like this: XXIX. Now you simply remove I and get XXX, which, in the Arabic system, means 30.
7. The so-called village idiot was smart enough to realize that as long as he kept choosing a 50-cent piece, people would keep offering him the choice. If he took the $5 bill once, the stream of coins would stop rolling in.
