  3. Detect the rule: Detect the rule in the sequence.
  4. Classify the type: Various types on which Coding and Decoding are classified are letter coding, substitution, mixed letter coding, and mixed number coding.

Coding Deductive Logic Types

How To Solve Questions on- Number Coding Deductive

Question 1.

In a certain code language, BICYCLE is coded as 293253125, how is SCOOTER written in the same code language?

Options:

A. 183151520617
B. 193151520518
C. 204161621715
D. 184151521517

Correct answer: B

Explanation:

[table id=693 /]

According to the table above the value under the alphabets are their codes. Therefore the code of SCOOTER on the basis of the table will be 193151520518.

Question 2.

If A = 1*2, B = 2*2, C = 3*2…….then KNOT is written as 120, how is DIVA written in the same code language?

Options:

A. 82
B. 52
C. 72
D. 62

Correct answer: C

Explanation:

Given, A = 1*2, B = 2*2, C = 3*2…. Z = 26*2. Value of each alphabets is multiplied by 2.

Therefore, for DIVA,
D = 4* 2 = 8
I = 9* 2 = 18
V = 22* 2 = 44
A = 1* 2 = 2
8 + 18 + 44 + 2 = 72

How To Solve-  Mixed Letter Coding Deductive/ Deciphering Messages

Question 1.

If ‘kun fun dung’ stands for ‘honey and sweets’; ‘sai dung fi hi’ stands for ‘sweets are loved’ and ‘nik dung di fug lo’ stands for ‘she cannot eat sweets,’ what would ‘dung’ stand for?

A. Honey
B. Sweets
C. And
D. Are

Correct answer: B

Explanation:

In all the three sentences, ‘honey and sweets,’ ‘sweets are loved,’ and ‘she cannot eat sweets,’ “sweets” is the common word. In all the three codes ‘kun fun dung,’ ‘sai dung fi hi,’ and ‘nik dung di fug lo,’ “dung” is common. Therefore, “dung” stands for “sweets.”

Question 2.

In a certain language:

‘248’ stands for ‘he is dead’
‘381’ stands for ‘dead or alive’
‘563’ stands for ‘sea or water’

Which digit stands for ‘alive?’

Options:

A. 4
B. 1
C. 8
D. 3

Correct answer: B

Explanation:

Common word in first and second sentence is ‘dead’ and common code is ‘8.’ Therefore code for ‘dead’ is ‘8.’ Common word in second and third sentence is ‘or’ and common code is ‘3.’ Therefore, code for ‘or’ is ‘3.’ So, in the second sentence only word ‘alive’ is left and code ‘1’ is left. Thus code for ‘alive’ is ‘1.’
