Which word could mean "ballroom"?
Explanation
Kes means foot; marro means ball; tolv means snow; and brin means man. The word marro, which means ball, is required at the start of ballroom. That rules out choices c and d, which begin with tolv (snow) and brin (man). Choice b is incorrect because marro comes at the end, which would put ball after room. That leaves choice a as the only possible answer.
Question 7
Here are some words translated from an artificial language.
taveln means joyful
koveln means joyless
pakveln means joyride
Which word could mean "joyous"?
taveln means joyful
koveln means joyless
pakveln means joyride
Which word could mean "joyous"?
Explanation
In this language the root word veln, which means joy, follows the suffix (ta, ko or pak). Therefore, in the word joyous, which also adds a suffix, the new part comes before the root. The only choice, then, is xanveln, because velnxan would put the new part after the root (the pattern used for a prefix), and choices c and d mean joyful and joyless.
Question 8
Here are some words translated from an artificial language.
plomteb means workshop
rekteb means workbook
zarnteb means workman
Which word could mean "homework"?
plomteb means workshop
rekteb means workbook
zarnteb means workman
Which word could mean "homework"?
Explanation
In this language the root word teb, which means work, follows the other part of the compound (plom, rek or zarn). Therefore, in the word homework, the parts are reversed: work comes first, then the new part. The only choice, then, is tebvesh, because veshteb would mean work plus another part, and choice c means workshop. Choice d does not contain teb at all.
Question 9
Here are some words translated from an artificial language.
ultolb means playful
gruntolb means playground
miktolb means playmate
Which word could mean "replay"?
ultolb means playful
gruntolb means playground
miktolb means playmate
Which word could mean "replay"?
Explanation
In this language the root word tolb, which means play, follows the suffix (ul, grun or mik). Therefore, in the word replay, the root word and the prefix would be reversed in the artificial language: the root comes first, then the new part. The only choice, then, is tolbxan, because xantolb would mean play plus a suffix, and choices c and d mean playmate and playground.

Question 22
The symbols @, #, $, * and % mean:
A@B = A>B.
A#B = A<=B.
A$B = A<B.
A*B = A=B.
A%B = A>=B.
Statements: X@Y, Y#T, T$V, V@R.
Conclusions:
I. X@V
II. X#V
III. V@Y
Which conclusion(s) are definitely true?
A@B = A>B.
A#B = A<=B.
A$B = A<B.
A*B = A=B.
A%B = A>=B.
Statements: X@Y, Y#T, T$V, V@R.
Conclusions:
I. X@V
II. X#V
III. V@Y
Which conclusion(s) are definitely true?
Explanation
X@Y, Y#T, T$V and V@R mean X>Y, Y<=T, T<V and V>R.
Chaining Y<=T and T<V gives Y<V, that is, V>Y. So conclusion III (V@Y) is definitely true.
X>Y and Y<V do not fix X against V, so neither conclusion I (X@V) nor conclusion II (X#V) can be determined.
Only conclusion III is definitely true.
Chaining Y<=T and T<V gives Y<V, that is, V>Y. So conclusion III (V@Y) is definitely true.
X>Y and Y<V do not fix X against V, so neither conclusion I (X@V) nor conclusion II (X#V) can be determined.
Only conclusion III is definitely true.
Question 23
The symbols @, #, $, * and % mean:
A@B = A>B.
A#B = A<=B.
A$B = A<B.
A*B = A=B.
A%B = A>=B.
Statements: F#R, R$T, T$V, W%V.

Statements: F#R, R$T, T$V, W%V.
Conclusions:
I. R$W
II. W@T
III. V@F
Which conclusion(s) are definitely true?
Explanation
F<=R, R<T, T<V, W>=V. Chaining R<T<V<=W gives R<W (conclusion I). Chaining W>=V>T gives W>T (conclusion II). Chaining F<=R<T<V gives F<V, i.e. V>F (conclusion III). All three are confirmed true.
Question 24
The symbols @, #, $, * and % mean:
A@B = A>B.
A#B = A<=B.
A$B = A<B.
A*B = A=B.
A%B = A>=B.
Statements: D@J, J*K, K%M, M$N.
Conclusions:
I. D@M
II. M#J
III. N*D
Which conclusion(s) are definitely true?
A@B = A>B.
A#B = A<=B.
A$B = A<B.
A*B = A=B.
A%B = A>=B.
Statements: D@J, J*K, K%M, M$N.
Conclusions:
I. D@M
II. M#J
III. N*D
Which conclusion(s) are definitely true?
Explanation
D>J, J=K, K>=M, M<N. Since J=K and K>=M, J>=M (confirming conclusion II, M<=J). Since D>J and J>=M, D>M (confirming conclusion I). N vs D (conclusion III) cannot be determined.
Question 25
The symbols @, #, $, * and % mean:
A@B = A>B.
A#B = A<=B.
A$B = A<B.

Which conclusion(s) are definitely true?
A@B = A>B.
A#B = A<=B.
A$B = A<B.
A*B = A=B.
A%B = A>=B.
Statements: R%M, M@V, V#W, W@T.
Conclusions:
I. R@V
II. M#W
III. R@W
Which conclusion(s) are definitely true?
Explanation
R>=M and M>V together give R>V (conclusion I confirmed), regardless of whether R=M or R>M. Neither M vs W nor R vs W can be pinned down from the remaining chain.
Question 26
The symbols @, #, $, * and % mean:
A@B = A is neither smaller than nor equal to B (A>B).
A#B = A is not greater than B (A<=B).
A$B = A is neither greater than nor equal to B (A<B).
A*B = A is neither greater than nor smaller than B (A=B).
A%B = A is not smaller than B (A>=B).
Statements: H@L, L*J, J$K, K%F.
Conclusions:
I. L*F
II. K@L
III. H@K
Which conclusion(s) are definitely true?
A@B = A is neither smaller than nor equal to B (A>B).
A#B = A is not greater than B (A<=B).
A$B = A is neither greater than nor equal to B (A<B).
A*B = A is neither greater than nor smaller than B (A=B).
A%B = A is not smaller than B (A>=B).
Statements: H@L, L*J, J$K, K%F.
Conclusions:
I. L*F
II. K@L
III. H@K
Which conclusion(s) are definitely true?
Explanation
H@L, L*J, J$K and K%F mean H>L, L=J, J<K and K>=F.
Since L=J and J<K, we get L<K, that is, K>L. So conclusion II (K@L) is definitely true.
Since H>L and L=J, we get H>J. This does not fix H against K, so conclusion III (H@K) cannot be determined.
The value of F relative to L is also not fixed, so conclusion I (L*F) cannot be determined.
Only conclusion II is definitely true.
Since L=J and J<K, we get L<K, that is, K>L. So conclusion II (K@L) is definitely true.
Since H>L and L=J, we get H>J. This does not fix H against K, so conclusion III (H@K) cannot be determined.
The value of F relative to L is also not fixed, so conclusion I (L*F) cannot be determined.
Only conclusion II is definitely true.
Question 27
A boy is asked to put in a basket one mango when ordered 'one', one orange when ordered 'two', one apple when ordered 'three', and to take out from the basket one mango and one orange when ordered 'four'. Given the sequence of orders: 1 2 3 3 2 1 4 2 3 1 4 2 2 3 3 1 4 1 1 3 2 3 4 -- how many oranges are there in the basket after this sequence?
Explanation
Tracking oranges added (order 2) and removed (order 4, one orange each time) through the full sequence step by step results in 2 oranges remaining in the basket.
Question 28
If every alternate letter of the English alphabet from B onwards (including B) is written in lower case, and the remaining letters are capitalized, how will the first month of the second half of the year be written?
Explanation
The first month of the second half of the year is July. Using the pattern (A capital by default, then alternating from B: b,C,d,E,f,G,h,I,j,K,l,M,n,O,p,Q,r,S,t,U,v,W,x,Y,z), J is lower, U is capital, L is lower, Y is capital, giving jUlY.
Question 29
If the code of ABCDEF is ZYXWVU, what is the code for PASS?
Explanation
The code reverses each letter's position in the alphabet (A<->Z, B<->Y, etc., i.e. letter x maps to the (27-x)th letter). P(16)->K(11), A(1)->Z(26), S(19)->H(8), S(19)->H(8), giving KZHH.
Question 30
In a certain code, CAT is written as SATC and DEAR is written as SEARD. How would SING be written in that code?
Explanation
The rule is: move the first letter of the word to the end, then prepend the letter S. CAT -> ATC -> SATC. DEAR -> EARD -> SEARD. Applying to SING: ING S -> INGS -> SINGS.
Question 31
In a certain code language, '134' means 'Good and Tasty', '478' means 'see good pictures' and '729' means 'pictures are faint'. Which numerical symbol stands for 'see'?
Explanation
The digit common to '134' and '478' is 4, so 4=Good. The digit common to '478' and '729' is 7, so 7=pictures. In '478', the remaining digit 8 must stand for 'see'.
Question 32
If BRIDGE is written as EULGJH in a certain code, how will FRUIT be written?
Explanation
Each letter of BRIDGE is shifted forward by 3 to get EULGJH (B->E, R->U, I->L, D->G, G->J, E->H). Applying the same +3 shift to FRUIT gives IUXLW.
Question 33
In a certain code, EASE is written as GUCG. How is CUT written in that code?
Explanation
The rule is: reverse the word, then shift each letter forward by 2. EASE reversed is ESAE; shifting each letter by +2 gives GUCG, matching. Applying the same rule to CUT: reversed is TUC, shifted by +2 gives VWE.
Question 34
In a certain language, NCL means PEN. What does GLI mean in that language?
Explanation
Each letter is shifted forward by 2 positions in the alphabet: N(+2)=P, C(+2)=E, L(+2)=N, giving PEN. Similarly for GLI: G(+2)=I, L(+2)=N, I(+2)=K, giving INK.
Question 35
In a certain language, CBE means BAD. What does GMBH mean in that language?
Explanation
Each letter is shifted back by 1 position in the alphabet: C(-1)=B, B(-1)=A, E(-1)=D, giving BAD. Similarly for GMBH: G(-1)=F, M(-1)=L, B(-1)=A, H(-1)=G, giving FLAG.
Question 36
In a certain language, '123' means 'bright little boy', '145' means 'tall big boy' and '637' means 'beautiful little flower'. Which digit in that language means 'bright'?
Explanation
'1' is common to the 1st and 2nd statements, and 'boy' is the common meaning, so 1 = boy. '3' is common to the 1st and 3rd statements, and 'little' is the common meaning, so 3 = little. This leaves '2' as the remaining digit in the 1st statement ('123' = 'bright little boy'), so 2 = bright. Since 2 is not among the given options, the answer is None of these.
Question 37
In a certain language, '123' means 'hot filter coffee', '356' means 'very hot day' and '589' means 'day and night'. Which digit in that language means 'very'?
Explanation
'3' is common to the 1st and 2nd statements, and 'hot' is the common meaning, so 3 = hot. '5' is common to the 2nd and 3rd statements, and 'day' is the common meaning, so 5 = day. This leaves '6' as the remaining digit in the 2nd statement ('356' = 'very hot day'), so 6 = very.
Question 38
In a certain language, 'they are fools' means 'plane is risky', 'we are wise' means 'train is fast' and 'wise never fools' means 'fast always risky'. Which word here stands for 'train'?
Explanation
'are' is common to the 1st and 2nd statements, and 'is' is the common meaning, so are = is. 'wise' is common to the 2nd and 3rd statements, and 'fast' is the common meaning, so wise = fast. This leaves 'we' as the remaining word in the 2nd statement ('we are wise' = 'train is fast'), so we = train.
Question 39
In a certain coded language, '3a 2b 7c' means 'truth is eternal', '7c 9a 8b 3a' means 'enmity is not eternal', and '9a 4d 2b 8b' means 'truth does not perish'. Which word means 'eternal' in that language?
Explanation
'9a' is common to the 2nd and 3rd statements, and 'not' is the common meaning, so 9a = not. '2b' is then common between the remaining parts of the 1st statement (truth, is, eternal) and 3rd statement (truth, does, perish), with 'truth' the shared meaning, so 2b = truth. This leaves {3a, 7c} = {is, eternal} in the 1st statement and {7c, 8b, 3a} = {enmity, is, eternal} in the 2nd, but no further statement distinguishes 3a from 7c, so which one means 'eternal' cannot be determined.
Question 40
In a certain language, 'pit nae tom' means 'apple is green', 'nae ho tap' means 'green and white', and 'ho tom ka' means 'shirt is white'. Which word represents 'apple' in this language?
Explanation
'nae' is common to the 1st and 2nd statements, and 'green' is the common meaning, so nae = green. 'ho' is common to the 2nd and 3rd statements, and 'white' is the common meaning, so ho = white. 'tom' is common to the 1st and 3rd statements, and 'is' is the common meaning, so tom = is. In 'pit nae tom' = 'apple is green', the remaining word pit must mean apple.
Question 41
In a certain language, 'ken poti' means 'good morning', 'hu shang' means 'come on', and 'hu ken sue' means 'come for good'. Which word in that language means 'for'?
Explanation
'ken' is common to 'ken poti' and 'hu ken sue', and 'good' is the common word in 'good morning' and 'come for good', so ken = good. 'hu' is common to 'hu shang' and 'hu ken sue', and 'come' is common to 'come on' and 'come for good', so hu = come. In 'hu ken sue' = 'come for good', removing hu (come) and ken (good) leaves sue = for.
Question 42
If 'rain' is called 'pink', 'pink' is called 'cloud', 'cloud' is called 'water', 'water' is called 'breeze' and 'breeze' is called 'moon', what would you use to wash your hands?
Explanation
Water is actually used to wash hands. Since 'water' is called 'breeze' in the given code, the answer is Breeze.
Question 43
If 'room' is called 'house', 'house' is called 'roof', 'roof' is called 'floor' and 'floor' is called 'terrace', what will a person stand on?
Explanation
A person actually stands on the floor. Since 'floor' is called 'terrace' in the given code, the answer is Terrace.
Question 44
If 'orange' is called 'butter', 'butter' is called 'soap', 'soap' is called 'ink', 'ink' is called 'honey' and 'honey' is called 'orange', which of the following is used for washing clothes?
Explanation
Soap is actually used for washing clothes. Since 'soap' is called 'ink' in the given code, the answer is Ink.
Question 45
If 'light' is called 'dark', 'dark' is called 'green', 'green' is called 'blue', 'blue' is called 'red', 'red' is called 'white' and 'white' is called 'yellow', what is the colour of blood?
Explanation
Blood is actually red in colour. Since 'red' is called 'white' in the given code, the answer is White.
Question 46
In a certain language, BOOK is coded as 43. What is the code for PEN?
Explanation
Each letter is coded by its position in the English alphabet and the positions are summed. BOOK: B(2)+O(15)+O(15)+K(11) = 43. Similarly, PEN: P(16)+E(5)+N(14) = 35.
Question 47
In a certain language, BODY is written as APCZ. How will DELHI be written in that language?
Explanation
The letters alternate between shifting back by 1 and forward by 1: B(-1)=A, O(+1)=P, D(-1)=C, Y(+1)=Z, giving APCZ. Similarly for DELHI: D(-1)=C, E(+1)=F, L(-1)=K, H(+1)=I, I(-1)=H, giving CFKIH.
Question 48
In a certain language, TRAIN is coded as RPYGL. What is the code for SCOOTER?
Explanation
Each letter is shifted backward by 2 positions in the alphabet (wrapping from A to Z): T(-2)=R, R(-2)=P, A(-2)=Y, I(-2)=G, N(-2)=L, giving RPYGL. Similarly for SCOOTER: S(-2)=Q, C(-2)=A, O(-2)=M, O(-2)=M, T(-2)=R, E(-2)=C, R(-2)=P, giving QAMMRCP.
Question 49
In a certain language, GOOD is written as HQRH. How will you write DREAM in that language?
Explanation
Each letter is shifted forward by its position in the word (1st letter +1, 2nd +2, 3rd +3, and so on): G(+1)=H, O(+2)=Q, O(+3)=R, D(+4)=H, giving HQRH. Similarly for DREAM: D(+1)=E, R(+2)=T, E(+3)=H, A(+4)=E, M(+5)=R, giving ETHER.
Question 50
In a certain language, DEAF is coded as 4. What is the code for ACE?
Explanation
The code represents the number of letters in the word. DEAF has 4 letters, giving code 4. Similarly, ACE has 3 letters, giving code 3.
Question 51
In a certain language, CONSTABLE is coded as 91. What is the code for STABLE?
Explanation
Each letter is coded by its position in the English alphabet and the positions are summed. CONSTABLE: C(3)+O(15)+N(14)+S(19)+T(20)+A(1)+B(2)+L(12)+E(5) = 91. Similarly, STABLE: S(19)+T(20)+A(1)+B(2)+L(12)+E(5) = 59.
Question 52
In a certain language, EGG is coded as 577. What should be the code for CAB?
Explanation
Each letter is coded by its position in the English alphabet: E = 5, G = 7, G = 7, giving EGG = 577. Similarly, C = 3, A = 1, B = 2, giving CAB = 312.
