You check the cupboards and find that you only have the following measuring cups: a 2/3 (two thirds) cup, and a 1/2 (half) cup. The muffin recipe requires exactly 1/3 of a cup of sugar. How can you accurately add this amount to the batter?

The Angry Astrologist

The angry astrologist has locked you up in a series of rooms. With your superior thinking abilities, you escape them one by one, until you reach the final room.

AQUARIUS – January-February

PISCES – February-March

ARIES – March-April

TAURUS – April-May

GEMINI – May-June

CANCER – June-July

LEO – July-August

VIRGO – August-September

You look around for more clues and stumble across something rather interesting. Above the door are three drawings from left to right: a set of scales, two fishes swimming in a circle, and a goat. Suddenly, the angry astrologist announces, “You have five minutes to escape. But if you enter the wrong code, you’ll be in for a huge surprise! Since my favorite holiday is coming soon, I’m feeling generous, so here’s a hint…just kidding! No hints! Hahahahaha!” The angry astrologist always talks in riddles, so you’re quite sure there was a hint in what she said. Time is running out! Can you figure out the 4-digit code?

That make kiss-y sounds

What are these cute little things?


On Valentine’s Day : The phone number is: 214-314-1984.Valentine’s Day is on February 14, which is 214.Pie is a Math term commonly represented as three digits: 3.14.George Orwell wrote a book called 1984.

John’s Car: Molly is the name of the car.

Making Muffins: Here are the steps to get a quarter cup of sugar into the batter:

* Fill the 2/3 cup with sugar

* Pour the sugar from the 2/3 cup into the 1/2 cup until the 1/2 cup is full. This leaves you with 1/6 of a cup of sugar in the 2/3 cup (Simple fractions:2/3 – 1/2 = 1/6)

* pour the 1/6 of a cup of sugar into the batter

* empty the 1/2 cup back into the sugar bag

* Repeat the above steps. You have now poured 1/6 of a cup of sugar into the batter TWICE, which gives you exactly 2/6, which is 1/3 of a cup of sugar

The Angry Astrologist: The correct code is 1031.The drawings on the wall represent the zodiacs: a set of scales = Libra, fishes= Pisces, goat = Capricorn. The table shows you which months those signscorrespond to.

LIBRA – September-October or 9-10

PISCES – February-March or 2-3

CAPRICORN – December-January or 12-1

Since the drawings are from left to right, you have several combinations to work with. The code can be any of the following:









You can eliminate all the non-4-digit codes, leaving you with only four possibilities. The final clue is in the angry astrologist’s announcement. She mentions, “my favorite holiday.” The only 4-digit code that is a holiday is 10-3-1.

Mystery Man : It’s Mario!

Lily’s Birthday: Guests must bring items that start with the last letter of their name. Forexample, “Eric” ends in C, so he brings cake.Sally can bring anything that starts with the letter Y: yogurt, yam, yoyo, etc.

Lost Time: Springfield and Louisville are in different time zones. Louisville is 1 hour ahead. After driving for 4 hours, it was 12:00 AM in Springfield, but already 1:00 AM in Louisville. That night while Jack was sleeping, Daylight Saving Time happened, and clocks moved forward by 1 hour. He slept for 8 hours and lost 1 hour, so he woke up at 10:00 AM.

Next Tuesday:  1 day. If tomorrow is two days before Tuesday, then tomorrow is Sunday. Then

today is Saturday. Two days from today is two days after Saturday, which is Monday. Counting from Monday, the number of days before it’s Tuesday is 1.

Strange Sentences: The odd one out is D. It is the only sentence in which the first letters of each

word doesn’t spell a school subject.

A) Matrices are too hard! (MATH)

B) Maracas, ukuleles, saxophones, Irish castanets. (MUSIC)

C) Human intentions strange; they often remember yesterday. (HISTORY)

D) Stars, planets, asteroids, comets. Endless. (SPACE)

E) So, can I eat now (chewing everything)? (SCIENCE)

A Simple Word Game:  “Field” refers to an enclosed area in a letter. For example, the letter A, D, and

O have one field, so they are worth 1 point. The letter B has two fields, so it is worth 2 points. Therefore, WORD GAME is worth 4 points.

A Strange Party: None. One of the two people that can shake hands with each other will

always be the first to say “hello,” or they all remain quiet.

Three Different Jobs: Since Mary is afraid of blood, she can’t be the nurse. And since she doesn’t like kids, she can’t be the elementary school teacher. So she must be the police officer. Steve doesn’t like kids, so he can’t be the elementary school teacher. And since Mary is the police officer, Steve must then be the nurse.

New Math: The “@” operation means three different Math operations: subtraction,

addition, and multiplication.


8@5 = {8-5}{8+5}{8×5} = {3}{13}{40} = 31340.

So 7@6 = {7-6}{7+6}{7×6} = {1}{13}{42} = 11342.

Family Day: He’s in the basement playing ping pong with Tracy.

Milk And Eggs: To solve this, you must know to which number key the letters in MILK and EGGS correspond:

1 = [blank]

2 = ABC

3 = DEF

4 = GHI

5 = JKL

6 = MNO

7 = PQRS

8 = TUV

9 = WXYZ

0 = [blank]

So, MILK = 6455, and EGGS = 3447.“MILK and EGGS” means you add the two numbers.

6455 + 3447 = 9902.

The phone’s password is 9902.

Two Lies And A Truth: Mindy is the one telling the truth.

Case #1:

Mark is lying, and Mindy confirms this by telling the truth. Mary is also lying

and is the smartest of the group.

Mary says, “I’m not.” – LIE

Mark says, “Mindy is.” – LIE

Mindy says, “Mark is lying.” – TRUTH

Case #2:

If Mary is telling the truth, then she’s not the smartest. If Mark is lying, then

Mindy is also not the smartest. But that means Mindy must be telling the

truth (that Mark is lying), and we can only have 1 truth teller.

Mary says, “I’m not.” – TRUTH

Mark says, “Mindy is.” – LIE

Mindy says, “Mark is lying.” – LIE

Case #3:

If Mary is lying, it means she’s the smartest. But if Mark is also telling the

truth, then Mindy is also the smartest, which is not possible.

Mary says, “I’m not.” – LIE

Mark says, “Mindy is.” – TRUTH

Mindy says, “Mark is lying.” – LIE

Penguin Escape: There are 3 zookeepers and 3 penguins. Here’s the plan to cross the river:

* 2 zookeepers and 1 penguin CROSS the river

* 1 zookeeper RETURNS

* 1 zookeeper and 1 penguin CROSS the river

* 1 zookeeper RETURNS

* 2 zookeepers and 1 penguin CROSS the river

All 3 zookeepers and penguins return to the zoo.

Cute Little Things: The answer is RATS.

“Grab one of these from the night sky” What’s in the night sky? Stars. “One of these” would be a STAR.

“And flip it around” If you flip STAR around, you get RATS.
