- 1. If in a certain language MYSTIFY is coded as NZTUJGZ, how is NEMISES coded in that code?
(a) MDLHRDR (b) OFNJTFT (c) ODNHTDR (d) PGOKUGU
Sol. Clearly, in the code, each letter is the alphabet next to the corresponding letter in
the word
M Y S T I F Y
N Z T U J G Z
So, for NEMISES, N will be coded as O,E as F, M as N and so on.
Answer is (b).
- 2. If TAP is coded as SZO, then how is FREEZE coded?
(a) ESDFYF (b) GQFDYF (c) EQDFYG (d) EQDDYD
Sol. Each letter in the code is the alphabet before the corresponding letter in the word.
S Z O
T A P
3. If CROWN is coded as BSNXM, how is BOARD coded?
(a) ANZQC (b) APZSC © CPBSE (d) CNBQE
Sol. Each letter is alternately one before and one ahead than the corresponding letter in the word.
So, B is coded as A, O as P, A as Z, R as S, D as C. hence, the answer is (b).
Thus, in FREEZE , F is coded as E, R as Q, E as D and Z as Y.
4. If TAIL is coded as VCKN, how is PEACE coded?
Sol.In the code each letter is two ahead than the corresponding letter in the word.
Thus, P is coded as R, E as G, A as C and C as E. so the answer is (a)
5. If LIGHT is coded as LJGIT , how is FLAMES coded?
(a) GLBNET (b) FKALER (c) FMANET (d) GLBMFS
Sol In the code, each letter is alternatively the same and one ahead than the
Corresponding letter in the word. So, in FLAMES, F is coded as F, L as M, A as
A, M as N, E as E and S as T.
The answer is (C)
- 6. In a certain code, SIKKIM is written as THLJJL how is TRAINING written in that code?
Sol: Clearly, the letters in the word SIKKIM are moved alternatively one step
forward and one step backward to obtain the letters of the code.
UQBHOHOF
- 7. In a certain code, FORGE is written as FPTJI how is CULPRIT written in that
code?
Sol:Clearly, the first letter in the word FORGE remains as it is and the second, third,
fourth and fifth letters are respectively moved one, two, three and four steps
forward to obtain the corresponding letters of the code.

============================================================
In each questions below are given two statements followed by two
conclusions numbered I and II. You have to take the two given statements to be
true even if they seem to be at variance from the commonly known facts and
then decide which of the given conclusion logically follows from the two given
statements, disregarding commonly known facts.
Give answer (a) if only conclusion I follows; (b) if only conclusion II follows; © if either I or II follows; (d) if neither I nor II follows; and (e) if both I and II follows.
8. Statements : All cakes are ice-creams.
All ice-creams are toffees.
Conclusions: I . All cakes are toffees.
II. All toffees are ice-creams.
Sol (a) Since both statements are affirmative, the conclusions must be
affirmative. Conclusion II cannot follow as it contains the middle term. So only
conclusion I follows
9. Statements : All tigers are ships
some ships are cupboards.
Conclusions: I some tigers are cupboards.
II some cupboards are tigers.
Sol. (d) the first premise is A type and distributes the subject. So, the middle
term 'ships', which forms its predicate, is not distributed.
The second premise is I type and does not distribute either subject or predicate.
So, middle term 'Ships' forming its subject is not distributed. Since the middle
term is not distributed at least once in the premises, no conclusion follows.
10. Statements : Some pearls are gems.
Some gems are ornaments.
Conclusions: I. Some gems are pearls.
II Some ornaments are gems.
Sol. (d) Since both the premises are particular, no conclusion follows.
