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!

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

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.

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
