Coding Decoding Question 1:

Here are some words translated from an artificial language:

migenlasan means cupboard

lasanpoen means boardwalk

cuopdansa means pullman

Which word could mean "walkway" ?

  1. cuopeisel
  2. poenforc
  3. poenmigen
  4. lasanpoen
  5. None of the above

Answer (Detailed Solution Below)

Option 2 : poenforc

Coding Decoding Question 1 Detailed Solution

The logic followed here is:

migenlasan means cupboard.

lasanpoen means boardwalk.

cuopdansa means pullman.

F1 State G Priya 24 4 2024 D10

Here, the code for board is lasan.

The code for walk is poen.

The code for cup is migen.

Now finding the possible word could mean "walkway".

Checking options one by one

Option (1): cuopeisel - As the code for walk is 'poen' the code must contain the term 'poen', so it is not the correct answer.

Option (2): poenforc - It has the term 'poen' in it and it is the only possibility left after eliminating other three options.

Option (3): poenmigen - As 'migen' is the code for cup it cant be the code for way.

Option (4): lasanpoen - As 'lasan' is the code for board it can't be the code for way.

Hence, the correct answer is "Option 2".

Coding Decoding Question 2:

  1. CGTF
  2. FTCG
  3. CTGF
  4. CFFT
  5. None of the above

Answer (Detailed Solution Below)

Option 1 : CGTF

Coding Decoding Question 2 Detailed Solution

The pattern for the code is as follows:-

F1 5f9c5787059f89f88b1ad963 Prashant.T 03-12-20 Savita D1

Similarly,

F1 Prashant Madhu 13.11.20 D6

Hence, READ will be written as CGTF.

Coding Decoding Question 3:

If JPG = 19 and PNG = 23, then TIF = ?

  1. 20
  2. 13
  3. 15
  4. 23
  5. None of the above

Answer (Detailed Solution Below)

Option 4 : 23

Coding Decoding Question 3 Detailed Solution

alphabet

The logic follows here is:

  • JPG → J(10) + P(16) - G(07) = 10 + 16 - 7 = 19

and,

  • PNG → P(16) + N14) - G(07) = 16 + 14 - 7 = 23

Similarly,

  • TIF → T(20) + I(9) - F(6) = 20 + 9 - 6 = 23

​Hence, the correct answer is "23".

Coding Decoding Question 4:

We know that,

RRB Group-D 17th Sep 2018 Shift 1 Q1 to Q100 (1) hindi हिंदी harish 36

The pattern followed here is as follows,

RRB Group-D 17th Sep 2018 Shift 1 Q1 to Q100 (1) hindi हिंदी harish 37

Similarly,

RRB Group-D 17th Sep 2018 Shift 1 Q1 to Q100 (1) hindi हिंदी harish 38

The pattern followed here is:

alpha teb

According to the alphabetical positions of the letters,

Logic is: Sum of the place value of the letters × Number of letters in the word

F1 Chitranshi 27-09-21 Savita D3

 SEND = 19 + 5 + 14 + 4 = 42 × 4 = 168

Similarly,

F1 Chitranshi 27-09-21 Savita D4

PURSE = 16 + 21 + 18 + 19 + 5 = 79 × 5 = 395 

Hence, ‘395’ is the correct answer.

Note:  This is SSC GD Previous year question paper and given answer as per the official answer key.

The letters are replaced by the place value of their reverse letter and then the numbers are added together to obtain the code.

Similarly,

5f7200e6e9d4487353a67867 16393843133051

Hence, ‘61’ is the correct answer.

Mistake PointsTOUCH = 20 + 15 + 21 + 3 + 8 =  67 and 67 + 1 = 68

ERROR = 5 + 18 + 18 + 15 + 18 = 74 and  74 + 1 = 75

75 is not in the options so the logic is different here.

The logic here is not sum of positional value + 1, but the logic here is sum of opposite positional value of letters.

In a certain code language, ‘ARROW’ is written as ‘FOOSE’ and ‘GERM’ is written as ‘THOR’. How will ‘MOWER’ be written in that language?

  1. SHORE
  2. ROSHE
  3. RSEHO
  4. HORSE

Answer (Detailed Solution Below)

Option 3 : RSEHO

Coding Decoding Question 14 Detailed Solution

Download Solution PDF

The logic followed here is:

 ‘ARROW’ is coded as ‘FOOSE’

F2 Madhuri SSC 12.04.2022 D6

‘GERM’ is coded as ‘THOR’

F2 Madhuri SSC 12.04.2022 D7

So, by observing the pattern, we can conclude that,

 A = F, R = O, O = S, W = E, G = T, E = H, R = O and M = R.

Now, we have to find the code for MOWER

As the codes of all the letters have been given in the question,

M = R, O = S, W = E, E =H, and R = O

Hence,

‘MOWER’ = ?

F2 Madhuri SSC 12.04.2022 D8

Hence, MOWER is coded as RSEHO.
