Question 1
1 / -0

In a certain code, 'FORGET' is written as 'DPPHCU'. How would 'DOCTOR' be written in that code?

A
BPAUMS

B
BPAUPS

C
EMDRPP

D
BPARPP

Solution

The letters at odd places i.e. 1st, 3rd, 5th are moved backwards by two letters. Thus, F becomes D, R becomes P and E becomes C and the letter at even place moves one letter forward, thus O becomes P, F becomes H and T becomes U. Therefore, in DOCTOR, D would become B, C would become A, O would become M.
Question 2
1 / -0

If BOX is coded as CDPQYZ, what will be the last two letters of word in the same code for HERO?

A
NM

B
MN

C
PQ

D
QP

Solution

Given, BOX is coded as CDPQYZ.
Here, each letter in the word BOX is moved one step forward to obtain the next two corresponding letters.
So, B coded as CD, O coded as PQ and X coded as YZ.
In the word, 'HERO' the last letter is 'O' which is coded as PQ.
Hence, option $$C$$ is the correct answer.
Question 3
1 / -0

Find the one that does not belong to the group.

A
$$\text{NKMJ}$$

B
$$\text{TQRP}$$

C
$$\text{URTQ}$$

D
$$\text{KHJG}$$

Solution

In all other groups except $$\text{TQRP}$$, there is a gap of one letter as in the alphabet between second and third letter.
So, the correct answer is option B.
Question 4
1 / -0

In a certain code 'PROSE' is written as 'PPOQE'. How is 'LIGHT' written in that code?

A
LIGFT

B
LLGFE

C
JIEHR

D
LGGFT

Solution

The letters at odd positions in the word remain same where the letters at even position move 2 steps backward in alphabetic order.
i.e.
R$$-2\rightarrow$$ P,
S$$-2\rightarrow$$ Q.
Similarly for LIGHT
I$$-2\rightarrow$$ G,
H$$-2\rightarrow$$ F.
So, the code for LIGHT is LGGFT.
Hence, option D is correct.
Question 5
1 / -0

If GOOD is written HQRH, how will you write DREAM?

A
ESPBN

B
ETHER

C
ETHPQ

D
ESHDR

Solution

$$GOOD$$ is coded as $$HQRH$$
$$G+1=H$$
$$O+2=Q$$
$$O+3=R$$
$$D+4=H$$
Then $$DREAM$$ will be coded as
$$D+1=E$$
$$R+2=T$$
$$E+3=H$$
$$A+4=E$$
$$M+5=R$$
Code is $$ETHER$$
Answer is Option $$B.$$
Question 6
1 / -0

In a certain code, PAINTER is written NCGPRGP, the REASON would be written as

A
PCYQMN

B
PGYQMN

C
PGYUMP

D
PGYUPM

Solution

The code is derived as follows for PAINTER.
P$$-$$2$$=$$N
A$$+$$2$$=$$C
I$$-$$2$$=$$G
N$$+$$2$$=$$P
T$$-$$2$$=$$R
E$$+$$2$$=$$G
R$$-$$2$$=$$P
Similarly, REASON will be coded as
R$$-$$2$$=$$P
E$$+$$2$$=$$G
A$$-$$2$$=$$Y
S$$+$$2$$=$$U
O$$-$$2$$=$$M
N$$+$$2$$=$$P
The code is PGYUMP.
Answer is Option $$C$$
Question 7
1 / -0

Four words are given, out of which three are same in one way and the fourth one is different from others. Select the odd one.

A
DBF

B
HFK

C
NLP

D
XVZ

Solution

The words DBF, NLP and XVZ follow a sequence where $$1^{st}$$ and $$2^{nd}$$ letter differ by $$-2$$ and $$2^{nd}$$ and $$3^{rd}$$ letters differ by $$+4$$ in alphabetic order.
So, DBF, NLP and XVZ follow a same sequence.
But in HFK, H and F differ by $$-2$$ and F and K differ by $$+5$$.
Thus, option B is different from others.
Hence, option B is correct.
Question 8
1 / -0

Find the odd one out from the alternatives.

A
$$130$$

B
$$60$$

C
$$24$$

D
$$6$$

Solution

$$ 6,24,60 $$ divisible by 6
$$130$$ is not divisible by 6
Hence $$130$$ is the odd number.
$$A$$ is the right answer.
Question 9
1 / -0

In a certain code, 'EASE' is written as 'GUCG'. How 'CUT' be written in that code?

A
UVD

B
DVU

C
VWE

D
EWV

Solution

The first and four letters are interchanged and second and third letters are interchanged. Then each letter is moved +2 steps. Thus, the code for 'CUT' is 'VWE'
Question 10
1 / -0

If VICTORY is codded as YLFWRUB, how can SUCCESS be coded ?

A
VFVVHFX

B
VXFFHVV

C
VYFFHVV

D
VXFFGVV
