Your toaster is broken, so you decide to toast your bread in a pan. The pan can hold three slices of bread at a time and takes 1 minute to toast one of their sides. How much time would it take you to toast four slices of bread on both sides using the pan?

It would take you 2 minutes and 40 seconds. Label the slices with A, B, C, D, their top sides A1, B1, C1, D1, and their bottom sides A2, B2, C2, D2.

1. Toast A1, B1, C1 for 40 seconds.
2. Toast A2, B2, D1 for 40 seconds.
3. Toast A1, C2, D2 for 20 seconds.
4. Toast A2, C2, D2 for 20 seconds.
5. Toast B1, C1, D1 for 20 seconds.
6. Toast B2, C2, D2 for 20 seconds.

## 100 Guests in 99 Rooms

One hundred people entered a hotel that had 99 rooms, and each of them asked for their own room. In order to solve the problem, the bellboy did the following:

He asked the 100th guest to wait for a while with the 1st guest in room number 1, so that there were 2 guests inside. Then he took the 3rd guest to room number 2, the 4th guest to room number 3, and so on, until finally taking the 99th guest to room number 98. At the end he returned to room number 1 and took the 100th guest to room number 99, which was still vacant.

How could everybody get their own room?

The two people who were taken to room number 1 were guest 1 and guest 100. Thus, the 2nd guest ended up without a room.

## Beaten and Burned

Ripped from my mother’s womb,
Beaten and burned, I become a bloodthirsty killer.

What am I?

## Died on the Fourth of July

During a trivia night, the following question appeared:

“Among the first five US presidents, Washington, Adams, Jefferson, Madison, and Monroe, there were 3 who died on the fourth of July. Can you guess which ones?”

After nobody answered the question, the following hint was given:

“These three presidents were consecutive ones.”

Then, all contestants immediately managed to answer the question. Can you?

Because of the way the question was worded, it was clear that the fifth president, James Monroe, was one of them. Otherwise, the trivia question would have been “among the first four US presidents” instead of “among the first five”. Since the three presidents that died on fourth of July were consecutive ones, they were Jefferson, Madison, and Monroe.

## Limbs

Partition the grid into disjoint “creatures”​, according to the following rules:

1. Each creature is defined as a shape of 4 connected branches that are each 1 cell wide.
2. For each creature, one of the branches ends up with a HEAD (always clued) and the other three branches end up with LIMBS (whenever clued, their directions matter).
3. A creature can never occupy a 2×2 region of cells and can never touch itself.

Examine the first example, then solve the other three puzzles.

The solutions are shown below.

Add a single letter at the end to create a meaningful word. You CANNOT add the letter E.

S E Q U E N C _

You should add the letter F above the underscore to create the letter E and get the word SEQEUNCE.

## 1 2 3 4 5 ?

Can you guess what the question mark should be replaced with? The answer is not 6.

The missing symbol is R, as in a car’s gears.

## Mammals in Cages
