12. As ACE stands for 135, so HERE stands for…
85185
85085
84175
83165

Each letter corresponds to a number, which depends on the position of the letter in the alphabet. A is in position 1, B in position 2, C in position 3, and so on. Thus A-C-E corresponds to 1-3-5, and H-E-R-E corresponds to 8-5-18-5

13. If o=3, t=1, w=0, s=2, x=6, i=0: what’s six divided by two?

15
12
14

132166914
132256914
134256912

Each letter corresponds to a number, which number depends on its position in the alphabet. A is in position 1, B in position 2, C in position 3, and so on. M U F F I N corresponds to: 13 21 6 6 9 14

20. If Eugene is 5 cm taller than Julie and Charles who is 10 cm taller than Julie measures 180 cm: how tall is Eugene?
175
170
180
185

We know that Charles is 180 cm tall. We know that Charles is 10 cm taller than Julie, so Julie is 170 cm tall. Eugene is 5 cm taller than Julie, so he is 175 cm tall.

21. How does this series of symbols end?
}{ , {} , {{ , ][ , [] , [[ , )( , …
() , ))
() , )(
(( , ()
() , ((

22. How does this series of numbers end? 9, 16, 25, 36, …
47
49
48
45

The formula behind the series is: INITIAL NUMB. + 7. NEW NUMB. + 9. NEW NUMB. + 11. NEW NUMB. + 13.

23. A contains one liter of water. You pour its contents into B which contains three-fifths of A, then you pour the contents of B into C which contains one-half of A: how much water remains in B?
0 liters
0.5 liters
0.1 liters
0.2 liters

A = 1 liter. B = 0.6 liters. C = 0.5 liters. So B minus C = 0.1 liters.

24. If t=2, x=11, e=13, ac=7: what is 131172?
Exact
Intact
Sect
Act

Each letter (or group of letters) corresponds to a number. In this way we can obtain a word by breaking up 131172 into its components. So we have 13-11-7-2, where 13=E, 11=X, 7=AC, 2=T (EXACT).

25. Louie’s height is exactly halfway between that of Margaret and Paul. Margaret is 165 cm tall, while Paul is 10 cm taller than Louie. How tall are Louie and Paul?
175 and 185 cm
165 and 170 cm
170 and 180 cm
175 and 180 cm

We know that Margaret is 165 cm tall. We know that Paul is 10 cm taller than Louie. We know that Louie is located halfway between Margaret and Paul. We can deduce that the difference between Louie and Margaret is also 10 cm, Louie being halfway between the two. So Louie is 175 cm tall and Paul is 185 cm.

26. If the sum of A, B and C is 60, and A is a half of C, while B is a half of C minus A: what are the values of A, B, C, respectively?
15, 15, 30
10, 10, 40
20, 0, 40
10, 30, 20

We know that C is twice as much as A. B, on the other hand, corresponds to C minus A. Knowing that A is half of C and B equals C minus A, we can conclude that A and B are both a half of C. If the total is 60, then A and B must equal 15, while C equals 30.

27. By anagramming the word CHEAP you can obtain a noun that has to do with:
Peace
Fruit
Air
Cost

By anagramming the word “CHEAP” you can obtain the word “PEACH”, which has to do with fruit.

28. If MYSELF + YOURSELF + THEMSELVES = 4, then THEMSELVES – YOURSELF – MYSELF = ?
0
1
2
3

The total is 4. MYSELF and YOURSELF are singular and their value is respectively 1 and 1. THEMSELVES is plural and its value must be 2. So: 2 minus 1 minus 1 = 0

29. How does this series of symbols continue?
\ , // , \| , { , }} , {| , [ , ]] , …
[
||
]|
[|

The full series is as follows:
\ , // , \| , { , }} , {| , [ , ]] , [|

30. You finish a race in 6th place. Then the 3rd contestant is relegated to 6th place, and the 7th contestant is moved to 5th place. What is your final position?
Sixth place
Fifth place
Seventh place
Fourth place

When the 3rd contestant is relegated to 6th place (the one you were in) you end up in 5th place. However, when the 7th contestant is moved up to 5th place (your new position) you end up in 6th place again.

31. I am short. All short people are nice. Most villains are obnoxious, while no obnoxious ones are short. Can a villain be short?
Only if he is obnoxious
Only if he’s also nice
Yes
No

This question is actually trivial. It is not stated anywhere that a villain cannot be short, nor it is stated that to be short he must also be likeable or unlikeable. Therefore, a villain can be short.

32. SPIDER stands to 4 + 4 as HORSE + SNAKE stands to:
3 + 3
2 + 2
0 + 0
1 + 1

The spider possesses 4 legs on each side of the body, for a total of 8 legs. The horse possesses 2 on one side and 2 on the other side, for a total of 4 legs. The snake possesses no legs. So horse + snake = 2 + 2.

33. What number do the question marks correspond to?

156
210
84
360

The table should be read from left to right, and the basic formula is the following:
FIRST NUMBER x ITSELF + FIRST NUMBER. SECOND NUMBER x ITSELF plus SECOND NUMBER.
(2×2) + 2 = 6 | (6 x 6) + 6 = 42
(3×3) + 3 = 12 | (12×12) + 12 = 156
(4×4) + 4 = 20 | (20×20) + 20 = 420

34. You have to cover a total of 1,000 meters. You travel the first 500 meters, then you move back 300 meters. How many meters do you have left to go?
800 meters
200 meters
700 meters
500 meters

The question is a tricky. You have to travel 1,000 meters in total. If you travel 500 in one direction and then another 300 in the opposite direction, that makes 800 meters in total. So you have 200 more to go.

35. If $16 $6 $14 &2 &2 = T H R E E , T H I N K = $16 $6 &3 $11 $8 , then K N I G H T =
$8 $11 &3 $5 $6 $16
$8 $11 &3 &5 $2 $16
$8 $11 &3 $5 $6 $14
&8 $11 &3 $5 $6 $16

This symbol & indicates a vowel, and the number that follows it (ex: &4) refers to its position in the alphabet. This symbol $ indicates a consonant, and the number that follows it (ex: $7) indicates its position in the alphabet. If you follow this logic you’ll have that K N I G H T corresponds to $8 $11 &3 $5 $6 $16
