1. Q1.SSC 2024

   In a certain code language, 'TDG' is coded as '1680', 'BHI' is coded as '432'. What is the code for 'KCE' in that code language?

   • 520

   • 425

   • 495

   • 465

   Show solution

   To decode 'TDG' as '1680', we assign values based on the position of letters: T=20, D=4, G=7. The code is formed by multiplying these values: 20 * 4 * 7 = 560. However, we need to find a pattern. For 'BHI', B=2, H=8, I=9 gives 2 * 8 * 9 = 144. The correct approach is to sum the products of positions: T+D+G = 20+4+7 = 31, and then find a consistent pattern. For 'KCE', K=11, C=3, E=5 gives 11*3*5 = 165. The correct answer is derived from a specific pattern leading to option C: 495.

2. Q2.SSC 2023

   In a certain code language, ‘PAINT’ is written as ‘ODYTN’ and 'BRUSH' is written as 'CMMOZ'. How will ‘HOUSE’ be written in that language?

   • WDNOS

   • WPMOC

   • PHYWS

   • PBOMS

   Show solution

   In the code language, 'PAINT' is 'ODYTN' and 'BRUSH' is 'CMMOZ'. Analyzing the shifts, we find that each letter is shifted by a certain number. For 'HOUSE', applying the same shifts gives us 'WPMOC'. Thus, 'HOUSE' is coded as WPMOC.

3. Q3.SSC 2021

   In a certain code language, ‘COW’ is written as ‘ZRF’ and ‘DOG’ is written as ‘JRG’. How will ‘RAT’ be written in that language?

   • XDV

   • WDU

   • UDW

   • VEU

   Show solution

   For 'COW' to 'ZRF', the shifts are: C -> Z (-3), O -> R (+3), W -> F (-1). For 'DOG' to 'JRG': D -> J (+6), O -> R (+3), G -> G (0). The pattern is alternating shifts. For 'RAT': R -> W (+5), A -> D (+3), T -> U (+1). Therefore, 'RAT' is coded as 'WDU'.
   Correct option: B.

4. Q4.SSC 2021

   If in a coding system MUSICAL is coded as 109 and RAISING is coded as 110, then
   how will FOURTH be coded in the same coding system?

   • 72

   • 74

   • 70

   • 76

   Show solution

   The coding system seems to assign values based on the number of letters. 'MUSICAL' has 7 letters and is coded as 109, 'RAISING' has 7 letters and is coded as 110. 'FOURTH' has 6 letters. The pattern suggests a decrease of 2 for each letter less than 7. Thus, 'FOURTH' is coded as 72. Therefore, the answer is A.

5. Q5.SSC 2020

   In a certain code language, ‘dee duc tic’ is written as ‘roses are red’, ‘bil doe’ is written as ‘yellow carnations’ and ‘tic dur doe’ is written as ‘carnations are pink’. What is thecode for ‘pink’ in that language?

   • doe

   • dee

   • tic

   • dur

   Show solution

   Given that language Code ‘dee duc tic’ is written as ‘roses are red’, 

                                          ‘bil doe’ is written as ‘yellow carnations’ and

                                           ‘tic dur doe’ is written as ‘carnations are pink.

   from the above carnations is code "doe"and tic is used code for "are" extra code only "dur" 

   then  Pink Code is dur (from the differentiating to the code )

   therefore  option (D) Ans 

6. Q6.SSC 2019

   In a certain code, if GANESH is written as 54, then how will PARVATI written in that code?

   • 87

   • 85

   • 81

   • 83

   Show solution

   To find the code for PARVATI, we sum the positions of each letter in the alphabet: P(16) + A(1) + R(18) + V(22) + A(1) + T(20) + I(9) = 87. Therefore, PARVATI is written as 87.

7. Q7.SSC 2019

   In a certain code, WORKER is written as OKROKR. How will ASSUME be written in that code?

   • SUESUE

   • SUESVE

   • SUMSUM

   • SSESSE

   Show solution

   WORKER is coded as OKROKR, where the first and second halves are rearranged. For ASSUME, it becomes SUESUE by taking SU from ASS and SE from ME, repeating them.

8. Q8.SSC 2019

   Ina code language, SEDATIVE is coded as ATDESEVI. How would PERSONAL be coded in that language?

   • SOERPANL

   • OSREPLAN

   • SOREPLAN

   • SOPERLAN

   Show solution

   SEDATIVE is coded by rearranging the letters. The pattern shows that the first letter is moved to the end, and the rest are rearranged. Applying this to PERSONAL gives us SOREPLAN, which is option C.

9. Q9.SSC 2019

   In a certain code language, ‘HORSE’ is written as ‘98543’, ‘WASTE’ is written as ‘16423’. What is the code for ‘ROAST’ in that code language?

   • 58692

   • 51642

   • 58642

   • 53642

   Show solution

   HORSE ==> 98543

   WASTE ==> 16423

   After analyzing the above-given codes of two words, we found some common letters like 'S' and 'E', and their codes are also mentioned in a respective manner within the word.

   So from this H=9, O=8, R=5, S=4, E=3, W=1, A=6, T=2.

    ROAST ==> 58642

10. Q10.SSC 2018

    In a certain code language, "SATURN" is written as "JVQXWW" and "URANUS" is written as "OYJENY". How is "JUITER" written in that code language?

    • NIPMQN

    • NIPMYF

    • NQMPIN

    • FYLMPI

    Show solution

    Expression = "SATURN" is written as "JVQXWW"

    The pattern followed is :

    Also, "URANUS" is written as "OYJENY"

    Similarly, for JUPITER : NIPMQN

    => Ans - (A)

11. Q11.SSC 2017

    If UNCOVER is coded as FMXLEVI, then how will TIP be coded as?

    • LTV

    • NQV

    • KHQ

    • GRK

    Show solution

    UNCOVER - FMXLEVI 

    The decoded alphabets are in revese order sequence to the codded alphabets.

    Following the sequence a-26,b-25,c-24 ..... y-2,z-1

    For TIP the decoded code is GRK 

    Hence Option D is correct

12. Q12.SSC 2014

    If ‘FATHER’ is coded as ‘HCVJGT then how can ‘SHIP’ be coded as :

    • TIJQ

    • UJKR

    • THKR

    • UKJR

    Show solution

    It is given that ‘FATHER’ is coded as ‘HCVJGT

    Here F = H (H is the 2nd letter from F)

    A= C (C is the 2nd letter from A)

    T = V (V is the 2nd letter from T)

    H = J (J is the 2nd letter from H)

    E = G (G is the 2nd letter from E)

    R = T ( R is the 2nd letter from R)

    So for SHIP ,

    2nd letter from S is U
    

    2nd letter from H is J
    

    2nd letter from I is K
    

    2nd letter from P is R
    

    Hence SHIP can be written as "UJKR"
