Number/Symbol1!2@3#4$5%6^7&8*9
         CodeTDCRGBYHNJPLQSDFZ


Conditions:
I. If the first element is an even number and the last is an odd number, the code for the first and last elements will be K.

II. If both the second and third elements are even numbers, the codes for these two are to be interchanged.

III. If the first element is a number and the last a symbol, the code for the first element is to be used for the last element also.

What will be the code for 2 $ 4 % 3 & ?

Correct Answer: (b) CHYJGC
Solution:

The factor given in the question “2$4%3&”
“2$4%3&” will be coded = CHYJGS
Replacing the code of the last element with the code of the first element as per condition (iii), we get
“2$4%3&” will be coded = CHYJGC

Number/Symbol4%58@$54^+#379
Code LetterGOHPTMABLNFSQR


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

(ii) If the first element is an odd number and the last element is an even number, the first and last elements are 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.

What will be the code for 5 @ $ ^ 8 ?

Correct Answer: (b) ©TML©
Solution:

The factor given in the question “5@$^λ 8”
“5@$^λ 8” will be coded = ATMLP
On interchanging the codes of first and last element as per condition (ii), we get
“5@$^λ 8” will be coded = ©TML©

         CodeGOHQTMABLMFSQR


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

(ii) If the first element is an odd number and the last element is an even number, the first and last elements are 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.

What will be the code for 3 @ 4 # 4 ?

Correct Answer: (b) ©TBF©
Solution:

The given factor in the question are “3@4#4”
“3@4#4” will be coded = STBFB
On Replacing the codes of first and last element with © as per condition (ii), we get
“3@4#4” will be coded = ©TBF©

How will ‘3 = 7 4 %’ be coded?

Correct Answer: (a) R V A M Y
Solution:

‘3 = 7 4 % ’
Since, the first element is number and the last element is a symbol then codes for these are to be interchanged.
As the given table, code for ‘3 = 7 4 % ’ = R V A M Y
