2. There is a bus with 7 children inside. Each child has 7 bags. Inside each bag there are 7 big cats. Each big cat has 7 small cats. All cats have 4 legs each. How many legs are on the bus?
Answer:
Now focus on first big cat :
1 2 3 4 5 6 7
1 2 3 4 5 6 7
Ø Each big cats have 7 small cats (that's the end of the focus)
Systematically, 7 small cats has 28 legs (7 * 4) combined with the big cat that owns this 7 small cats.
Systematically, 7 small cats has 28 legs (7 * 4) combined with the big cat that owns this 7 small cats.
Let's call this the "cat chain", so cat chain 1 has 32 legs altogether.
Ø So since there are 7 big cats
7 * 32 = 224 legs
Ø So since there are 7 big cats
7 * 32 = 224 legs
Ø Therefore each backpack has 224 legs
Ø Finally, each girl has 7 * 224 = 1568 legs.
Lastly, since there are 7 girls, A to G, there are 7 * 1568 legs (per girl) = 10976 legs.
Now, since each girl also has 2 legs each;
SO, (7 * 2) + 10976 = 10990 legs altogether

Answer: The error is found in the "lll". Instead of being capital i's, they are lower-case L's and only appear to be i's. The correct form would be "... HHH III JJJ ..." and not "...HHH lll JJJ...".

9. Three travelers register at a hotel and are told that their rooms will cost $10 each so they pay $30. Later the clerk realizes that he made a mistake and should have only charged them $25. He gives a bellboy $5 to return to them but the bellboy is dishonest and gives them each only $1, keeping $2 for himself. So the men actually spent $27 and the bellboy kept $2. What happened to the other dollar of the original $30?
Answer: There is no missing dollar from the original $30 because after getting $1 back, the three travelers had paid a total of $27 for their room ($9 each), not $30. Out of that $27, the hotel has $25 and the clerk kept the remaining $2. If you still want to work from the original $30, the travelers have $3, the hotel has $25 and the bellboy has $2. The misleading part is adding the bellboy's $2 to the $27, when in fact it should be subtracted
