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


Conditions:

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

(ii) If the first element is an odd number and the last element is an even number, then the codes of these two should be interchanged.

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

What will ‘5 @ 2 @ 6’ be coded as?

Correct Answer: (b) FEGPTC
Solution:

Given series : 5 < = 2 @ 6
It will be coded as : CEGPTF
Only condition (ii) follows here.
After interchanging the codes for first and last element, final series will be :
FEGPTC

Number / Symbol@%!425#?+=3&7<
      CodeCLNDMBRAPJXWEH


Conditions:

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

(ii) If the first element is an odd number and the last element is an even number, then the first and last elements will be coded as Φ.

(iii) If both the second and third elements are either numbers or symbols, then the third element will be coded as the code for the second element.

Question: How will ‘% + < 2 5 =’ be coded for?

Correct Answer: (c) LPPMBJ
Solution:

Given: % + < 2 5 =
Here, Second and third element is a symbol, so third element is coded as the code for the second element.
Now, “% + < 2 5 =” is coded as L P P M B J

39. In a certain code language, MUTINY is written as 25149202113 and MAGIC is written as 397113. How will NECTAR be written in the same language? [Group – D 25/08/2022 (Afternoon)]

Correct Answer: (b) 181203514
Solution:

(Code language is written as the place value of the alphabets after reversing the given words.) i.e.
MUTINY → YNITUM → Y(25), N(14), I(9), T(20), U(21), M(13) → 25149202113
And MAGIC → CIGAM → C(3), I(9), G(7), A(1), M(13) → 397113
Similarly, NECTAR → RATCEN → R(18), A(1), T(20), C(3), E(5), N(14) → 181203514

40. 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 25/08/2022 (Evening)]


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 third and the fourth elements are prime numbers, the fourth element is to be coded as the code for the third element and vice versa.

Question: 2675$!

Correct Answer: (d) WSECUY
Solution:

As the condition (i) and (iii) follows the following question.
So, according to condition (i), after interchanging the codes of first and last elements we get: W S E C U Y
Now, according to condition (iii),
After interchanging the codes of third and fourth elements we get: W S C E U Y
