How to Solve Coding and Number Series Questions Quickly :

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……….

Options:

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?

Options:

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

Question 5: 

If the word is KEYBOARD written as LGBFTGYL then, what will be the code for INTERNET ?

A)JPWHUPHW
B)JPHWIUYTP
C)JPWIWTLB
D)None of the above

Explanation:
The 1st, 2nd, 3rd ………. And so on alphabet of the word are moved 1, 2, 3….. Steps forward respectively.
KEYBOARD will be coded as LGBFTGYL
INTERNET will be written as JPWIWTLB
