Question 1
1 / -0

If OLYMPICS is coded as PMZNOHBR, and JUMP is coded as KVLO, then COMPUTER will be coded as........

A
DPNQVUFS

B
DPNQTSFQ

C
DPNQTSDQ

D
BNLOTSDQ

Solution

$$O\overset{+1}{\rightarrow}P$$
$$L\overset{+1}{\rightarrow}M$$
$$Y\overset{+1}{\rightarrow}Z$$
$$M\overset{+1}{\rightarrow}N$$
$$P\overset{-1}{\rightarrow}O$$
$$I\overset{-1}{\rightarrow}H$$
$$C\overset{-1}{\rightarrow}B$$
$$S\overset{-1}{\rightarrow}R$$
Same as
$$C\overset{+1}{\rightarrow}D$$
$$O\overset{+1}{\rightarrow}P$$
$$M\overset{+1}{\rightarrow}N$$
$$P\overset{+1}{\rightarrow}Q$$
$$U\overset{-1}{\rightarrow}T$$
$$T\overset{-1}{\rightarrow}S$$
$$E\overset{-1}{\rightarrow}D$$
$$R\overset{-1}{\rightarrow}Q$$
Question 2
1 / -0

Find the missing term in the Following sequence
A, C, H, R, ?, I, T

A
H

B
I

C
J

D
K

Solution

There is only one alphabets between A and C$$= 1$$. There are $$4$$ alphabets between C and H $$\displaystyle =2^{2}$$ There are 9 alphabets between H and R $$\displaystyle =3^{2}$$ So, the difference beween R and the missing alphabet should be that of $$\displaystyle =4^{2}=16$$ alphabets. One cycle of $$26$$ alphabets gets over and then the same cycle starts. So, the missing the alphabet is I. Similarly, the difference between I and I is that of $$\displaystyle =5^{2}=25$$ alphabets and the difference between I and T will be that of $$\displaystyle =6^{2}=36$$ alphabets.
Question 3
1 / -0

Find the wrong term of the following series
2, 6, 11, 17, 23, 32, 41

A
6

B
17

C
23

D
32

Solution

Given series is 24 Hence the wrong term is 23
Question 4
1 / -0

If RADIO is written as PYBGM, then how would OQDKNG be written in that code ?

A
MOBIEL

B
MOBLIE

C
MOIBLE

D
MOBILE

Solution

Given, RADIO is written as PYBGM. The coding pattern for the same is:
R $$\underrightarrow { -2\quad } $$ P
A $$\underrightarrow { -2\quad } $$ Y
D $$\underrightarrow { -2\quad } $$ B
I $$\underrightarrow { -2\quad } $$ G
O $$\underrightarrow { -2\quad } $$ M
Similarly, OQDKNG is coded as follows:
O $$\underrightarrow { -2\quad } $$ M
Q $$\underrightarrow { -2\quad } $$ O
D $$\underrightarrow { -2\quad } $$ B
K $$\underrightarrow { -2\quad } $$ I
N $$\underrightarrow { -2\quad } $$ L
G $$\underrightarrow { -2\quad } $$ E
Hence, OQDKNG is writen as MOBILE.
Therefore, option (D) is the correct answer.
Question 5
1 / -0

If CRICKETER is coded as DQJBLDUDS, then PLAYER will be coded as :

A
QMBZFS

B
OMZZOS

C
QKBXFQ

D
OKBZOS

Solution

Given, CRICKETER is coded as DQJBLDUDS. The coding pattern for the same is:
C $$\underrightarrow { +1\quad } $$ D
R $$\underrightarrow { -1\quad } $$ Q
I $$\underrightarrow { +1\quad } $$ J
C $$\underrightarrow { -1\quad } $$ B
K $$\underrightarrow { +1\quad } $$ L
E $$\underrightarrow { -1\quad } $$ D
T $$\underrightarrow { +1\quad } $$ U
E $$\underrightarrow { -1\quad } $$ D
R $$\underrightarrow { +1\quad } $$ S
Similarly, PLAYER is coded as follows:
P $$\underrightarrow { +1\quad } $$ Q
L $$\underrightarrow { -1\quad } $$ K
A $$\underrightarrow { +1\quad } $$ B
Y $$\underrightarrow { -1\quad } $$ X
E $$\underrightarrow { +1\quad } $$ F
R $$\underrightarrow { -1\quad } $$ Q
Hence, PLAYER is coded as QKBXFQ.
Therefore, option (C) is the correct answer.
Question 6
1 / -0

P and Q are married couple, A and B are brothers, A is the brother of P. How is B related to Q

A
Brother

B
Sister

C
Brother-in-law

D
Sister-in-law

Solution
Question 7
1 / -0

If the word EARTH be written as QPMZS in coded form, how can be HEART be written in that code?

A
SQPZM

B
SQMPZ

C
SPQZM

D
SQPMZ

Solution

Given the code for EARTH,
Letter E A R T H
Code Q P M Z S
Following as above, code for HEART becomes SQPMZ.
(option D)
Question 8
1 / -0

If CEG is written as TSR and FHJ is written as QPO, then IKM is written as

A
NOP

B
PON

C
MLK

D
NML

Solution

The given two codes can be deciphered as seen in the figure.
So, the letters IKM must move by (5,2,-1) respectively to get the sequence (N,M,L) (option D).
Question 9
1 / -0

In a certain code, 'MONKEY' is written in as XDJMNL, how is 'TIGER' written in that code?

A
SHFDQ

B
QDFHS

C
SDFHS

D
QDHJS

Solution

The letters of the word are first written in reverse order & then moved one step backward. So, TIGER becomes REGIT and then
R E G I T
$$-1\downarrow \ \ -1\downarrow \ \ -1\downarrow \ \ \ -1\downarrow \ -\ 1\downarrow$$
Q D F H S
(option B)
