How To Solve Coding And Number Series Quickly

How To Solve Coding And Number Series Quickly:-

Letter-Number Coding is a mark scoring section of the reasoning questions.  In competitive examinations reasoning contain a most important part. If you achieve good marks in reasoning you will get a good score and rank in competitive examinations.

The best way to understand Number series coding is by going through its solved questions. Reasoning is all about more and more practice. Here are a few solved Questions to help you in a better way.

Question 1

If in a certain language A is coded as 1, B is coded as 2, and so on, how is B I D D I C coded in that code?

Option:

A) 294493
B) 284563
C) 375582
D) 394492

Answer: A

Explanation:

As given the letters are coded as:

A   B   C   D   E   F   G   H   I
1    2   3    4    5   6    7   8    9
So, in B I D D I C, B is coded as 2, I as 9, D as 4, and C as 3. Thus, B I D D I C is coded as 294493.

Question 2

If D is coded as 4 and C O V E R is coded as 63, then BASIS will be coded as?

Option:

A) 54
B) 55
C) 49
D) 50

Answer: D

Explanation:

It is clear that the code is arrange in this mannerA = 1. B = 2, C = 3 … so on

so that C O V E R is coded as  [C+O+V+E+R]

⇒ 3 + 15 + 22 + 5 + 18 = 63.

Now B A S I S is coded as [ B+A+S+I+S]

⇒2 + 1 + 19 + 9 + 19 = 50.

Question 3

bcd’ is coded as ‘def’ then ‘True’ is coded as……….

Option:

A) Hynx
B) Vrwx
C) Zbyw
D) Vtwg

Answer: D

Explanation:

b – d (+2)
c – e (+2)
d – f (+2)
+2 letters are considered in this code.
True – Vtwg

Question 4

In a certain code ‘MONARCHY’ is written as ‘NPOBSDIZ’. How will ‘STANDARD’ be written as in that code?

Option:

A) TUBOEBSE
B) TVBSHBNW
C) WEHJSOLX
D) GHWQMKLJ

Answer : A

Explanation:

Each letter of MONARCHY is replaced by the next letter as per  the alphabet

M+ 1 = N
O+ 1 = P
N+ 1 = O
A+ 1 = B
R+ 1 = S
C + 1= D
H+ 1 = I
Y+ 1 = Z

Similarly STANDARD is written as TUBOEBSE
