Number / Symbol1%84∅∂2$!6=375
        CodeAEIOUPRTVXZBDF


Conditions:

(i) If the first element is a number and the last a symbol, the codes for these two (the first and the last elements) are to be interchanged.

(ii) If the first element is an EVEN number and the last an ODD number, the first and last elements are to be coded as &.

(iii) If both the second and the third elements are prime numbers, the third element is to be coded as the code for the second element.

Question: 2 $ 3 7 3

Correct Answer: (d) &TBD&
Solution:

Question: 2 $ 3 7 3
Code for above question : R T B D B
Since, the question follows only condition (ii), then according to condition (ii),
By replacing the code for first and last element by & , we get,
2 $ 3 7 3 → & T B D &

47. In this question, a set of numbers/symbols are to be coded using letters as per the table given below followed by the conditions given below. The correct combination of the codes following the conditions is your answer. [Group – D 26/08/2022 (Evening)]


(Reference: Letter/Symbol - Code)

Terms:

(i) If the first element is a number, and the last element is a symbol, then the codes of these two (first and last elements) should be interchanged.

(ii) If the first component is an even number and the last component is an odd number, then the first and the last components shall be coded as “!”.

(iii) If both the third and fourth components are prime numbers, then the fourth component is coded as the code for the third component, and the third component is coded as the code for the fourth component.

Question: 8 $ 5 2 @

Correct Answer: (d) AVGKT
Solution:

The factors given in the question are “8 $ 5 2 @”.
“8 $ 5 2 @” will be coded ⇒ T V K G A
On interchanging the codes of first and last element as per condition (i), we get
T V K G A ⇒ A V K G T
On interchanging the codes of third and fourth components as per condition (iii), we get
A V K G T ⇒ A V G K T

48. 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 29/08/2022 (Morning)]

Number / Symbol-$68<?/25!@73^
        CodeGLFMENDPCRTBVA


Conditions:

(i) If the first element is a symbol and the last a number, then the first and last elements are to be coded as © and ¥ respectively.

(ii) If the first element is an odd number and the last an even number, the codes for these two are to be interchanged.

(iii) If both the second and third elements are perfect squares, the third element is to be coded as the code for the second element.

Question: How will ‘5 $ = 2 ^ 8’ be coded?

Correct Answer: (a) MLG PAC
Solution:

The factors given in the question are 5$=2^8
5$=2^8 will be coded = CLGPAM
The second condition is applied to this group of numbers/symbols according to the given condition condition says that coded of first and last element is interchange
( 5 = M, $ = L, G = 2, P = ^, A = 8 = C)
5$ = 2^8 = M L G P A C

49. 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 condition is your answer. [Group – D 29/08/2022 (Afternoon)]

Number / Symbol8=/&37@$2<%6+4
        CodeFRDSZBPKUHYXTG


Conditions:

(i) If the first element is a symbol and the last a number, the first element is to be coded as the code for the last element.

(ii) If the first element is a number that is completely divisible by 3, it is to be coded as ⊗.

(iii) If both the second and third elements are perfect squares, the third element is to be coded as the code for the second element.

Question: How will ‘6 @ & 4 =’ be coded?

Correct Answer: (b) ⊗PSGR
Solution:

The elements given in the question are “6 @ & 4 =”.
“6 @ & 4 =” will be coded ⇒ “X P S G R”
On interchanging the codes of first element with ⊗ as per condition (ii), we get
“6 @ & 4 =” will be coded ⇒ “⊗ P S G R”
