#1. In a certain code FIRE is coded as DGPC. What will be the last letter of the coded word for SHOT.

Answer: Option B
Solution:

D is used for F.
G is used for I.
P is used for R.
and
C is used for E. Thus, it is clear that each letter of the word FIRE stands for each corresponding letter of the coded word DGPC two places ahead. By applying the same principle, the letters QFMR will stand for SHOT. Hence, the last letter of the coded word is R.

#2. If TOUR is written in a certain code as 1234, CLEAR as 56784 and SPARE as 90847, what will be the 5th digit for SCULPTURE in the same code ?

Answer: Option D
Solution:

By, comparing letters and digit, we get
T = 1
O = 2
U = 3
R = 4
C = 5
L = 6
E = 7
A = 8
S = 9 and
P = 0
As the 5th letter is SCULPTURE is P and ‘0’ is used for P, therefore, 5th digit is the required code which is ‘0’.

#3. If in a certain language PROSE is coded as PPOQE, how is LIGHT coded in that code ?

Answer: Option C
Solution:

In the given code

PROSE = PPOQE

The first, third and fifth letters are same but in the place of second and fourth letters previous two letters are used. So,
LIGHT = LGGFT.

#4. If SUMMER is coded RUNNER, the code for WINTER is

Answer: Option B
Solution:

SUMMER = RUNNER

In the given code, second, fifth and sixth letters are same. The first letter of the word (S → R) is moved one step backward, while the two middle letters (M → N and M → N) each moved one step forward to obtain the corresponding letters of the code. So,

WINTER = VIOUER.

#5. If MIND becomes KGLB and ARGUE becomes YPESC, then what will DIAGRAM be in that code ?

Answer: Option A
Solution:

MIND = KGLB

Each letter in the word is moved two steps backward to obtain the corresponding letter of the code. So,

DIAGRAM = BGYEPYK.

#6. In a certain language PRACTICE is coded as PICCTRAE, how is FLAMES coded in that code ?

Answer: Option C
Solution:

PRACTICE = PICCTRAE.
First and last letters are same but second and third letters and third last and second last letters have been interchanged.
So,
FLAMES = FMELAS.

#7. If the KNIFE is coded as MPKHG, what do the letters DTGCF stand for ?

Answer: Option B
Solution:

KNIFE = MPKHG.
Each letters of the word KNIFE stand for each corresponding letter of the word MPKHG, two places ahead.
So,
BREAD = DTGCF.

#8. If the letters GBOQX stand for HAPPY , for which word the letters CROSS stand for ?

Answer: Option B
Solution:

GBOQX = HAPPY
First letter of the word HAPPY is next letter of the first letter of the word GBOQX and second letter of the word HAPPY is the previous letter of the second letter of the word GBOQX. This order is further repeated.
So,
CROSS = BSNTR.

#9. If in a certain language SISTER is coded as 535301 , UNCLE is coded as 84670 and BOY as 129 , how son is coded ?

Answer: Option B
Solution:

we have, S = 5
I = 3
T = 3
E = 0
R = 1
U = 8
N = 4
C = 6
L = 7
B = 1
O = 2
Y = 9.
So,
SON = 524.

#10. If HARD is coded s 1357 and SOFT is coded as 2468, what do the figures 21448 stand for ?

Answer: Option D
Solution:

H = 1
A = 3
R = 5
D = 7
S = 2
O = 4
F = 6
T = 8.
Hence,
21448 = SHOOT.
