1. In this question, a group of numbers/symbols is coded using letters as per the table given below and the conditions which follow. The correct combination of codes following the conditions is your answer. [Group – D 17/08/2022 (Morning)]

Number / Symbol75E%&48
CodeSDMUTLA


Conditions:
(i) If the second element is an odd number and the last element is an even number, the codes for these two (the second and the last elements) are to be interchanged.

(ii) If the third element is an even number and the fifth element is a symbol, the codes for these two (the third and the fifth elements) are to be interchanged.

(iii) If the fifth element is a symbol but the sixth element is also a symbol, both these elements (the fifth and the sixth elements) are to be coded as R.

Question: E 7 5 % & 4 8

Correct Answer: (d) MADUTLUS
Solution:

The components given in the question are “E75%&4%8”
“E75%&4%8” is coded as → MSDUTLUA
In this question, condition(i) is implied, so we have to interchange the codes of second and last elements.
then “E75%&4%8” will be coded as MADTULUS.

2. n a certain code language, ‘FUEL’ is written as ‘50’ and ‘JEER’ is written as ‘44’. How will ‘FARE’ be written in that language? [Group – D 17/08/2022 (Afternoon)]

Correct Answer: (d) 36
Solution:

FUEL = (6 + 21 + 5 + 12) + 6 = 44 + 6 = 50
JEER = (10 + 5 + 5 + 18) + 6 = 38 + 6 = 44
Similarly,
FARE = (6 + 1 + 18 + 5) + 6 = 30 + 6 = 36

3. In a certain code language, ‘ACADEMY’ is written as ‘FSJHDEB’ and ‘BARRIER’ is written as ‘YKNVUCC’. How will ‘ATTEMPT’ be written in that language? [Group – D 22/08/2022 (Morning)]

Correct Answer: (a) AVRIRWB
Solution:

4. In a certain code language, ‘CREAM’ is written as ‘FUVEQ’ and ‘STOVE’ is written as ‘VWLZI’. How will ‘PITCH’ be written in that language? [Group – D 30/08/2022 (Afternoon)]

Correct Answer: (b) SLGGL
Solution:

5. In a code language, ‘we prefer green’ is written as ‘yo ha ni’, ‘green peas grow’ is written as ‘ki mi yo’, and ‘we grow herbs’ is written as ‘zu ha mi’. What is the code for the word ‘prefer’ in that language? [Group – D 30/08/2022 (Afternoon)]

6. In a certain code language, ‘SYMBOLIC’ is written as ‘CPTZNMJD’ and ‘SYMPATHY’ is written as ‘QBTZNUIZ’. How will ‘SURVIVAL’ be written in that language? [Group – D 09/09/2022 (Evening)]

Correct Answer: (d) WJTVSWBM
Solution:

7. In a certain code language, ‘CHERRY’ is coded as ‘6-16-10-36-36-50’, and ‘GRAPES’ is coded as ‘14-36-2-32-10-38’. How will ‘LITCHI’ be coded in that language? [NTPC CBT II Level 5 (15/06/2022) Shift 2]

Correct Answer: (d) 24 - 18 - 40 - 6 - 16 - 18
Solution:

C → 3 × 2 = 6
H → 8 × 2 = 16
E → 5 × 2 = 10
R → 18 × 2 = 36
R → 18 × 2 = 36
Y → 25 × 2 = 50
Similarly,
L → 12 × 2 = 24
I → 9 × 2 = 18
T → 20 × 2 = 40
C → 3 × 2 = 6
H → 8 × 2 = 16
I → 9 × 2 = 18

8. In a certain code language, ‘TEACHING’ is written as ‘GVZXSRMT’, ‘TENDENCY’ is written as ‘GVMWVMXB’. How will ‘SYMBOLIC’ be written in that language? [NTPC CBT II Level 2 (16/06/2022) Shift 1]

Correct Answer: (c) HBNYLORX
Solution:

Write opposite letters of given letters
TEACHING ⇒ GVZXSRMT
TENDENCY ⇒ GVMWVMXB
Similarly,
SYMBOLIC ⇒ HBNYLORX

9. In a certain code language, ‘MOMENTUM’ is written as ‘EMONNTUM’ and ‘EQUATION’ is written as ‘AUQETION’. How will ‘MAGNETIC’ be written in that language? [NTPC CBT II Level 2 (16/06/2022) Shift 3]

Correct Answer: (d) NGAMETIC
Solution:

10. In a certain code language, ‘CUP’ is coded as ‘DAO’ and ‘RAN’ is coded as ‘SEM’. How will ‘BAD’ be coded in that language? [NTPC CBT II Level 3 (17/06/2022) Shift 1]
