CODING-DECODING
certain way
are use to communicate the message that cannot understand other person if they
cannot understand the logic proper way.
This chapter have this logic that have some alphabetic or numeric or
combination of both are used.

1. BEAT:YVZG then
MILD is realted to…
BEAT is 2,5,1,20 number letter from beginning of English alphabet and YVZG
is 2,5,1,20 number letter
from end of English alphabet . thus MILD
is 13,9,12,4 letter from beginning thus find character that is 13,9,12,4 letter from end. Thus “NROW” is
correct answer.
2. If in ceratin code O is written as E, A as C,M
as I, S as O,N as P,E as M,I as A, P as N ,C as S,
Then
how COMPANIES is code ?
HERE “c” as “ s”,“o”
as “e ”,“m” as “i ”,“p” as “ n ”,“a” as “c ”,“n”
as “ p ”,“i” as “ a”,“e”
as “ m ”,“s” as “ o ”.
Thus “seincpamo” is correct answer.
3. If E=5 ,PEN=35,then PAGE is
Here logic is “E” is 5 of English alphabet.now
p=16,E=5,N=14
PEN=16+5+14=35
Therefore PAGE=16+1+7+5=29
4.
In each of the
following question, a word is represented by only one set of numbers as given
in any one of the alternatives.The sets of numbers given in the alternatives
are represented by two clauses of alphabets as in the two given matrices .the
columns and rows of matrices 1 are numbered from 0 to 4 and those of matrices 2
from 5 to 9. A letter from these matrices can be represented first by its row
and then the column number example , in the matrices for question 1 to 4 , M
can represented as 14,21 etc; O is represented by 20,32 etc .similarly you have
to identify the correct set for the word given in each question.

MOST
a) 40,44,22,89
b) 33,20,11,79
c) 21,oo,03,88
d) 02,13,34,56
in this type of
question two matrix are given have have
to find corresponding letter in both
matrix. So best to tackle the this problem is
compare each character to all given option
therefore
m=>02
o=>13
s=>34
t=>56
thus d) option is correct.
5. If “ black” means “pink”,”pink” means
“blue”,”blue”means “white”,”white” means “yellow”,”yellow” means “red”,”red”
means “brown”.then what is color of sky ?.
a) Brown b) red
c) blue d) pink e)
none of these
Here actually sky color is black so black is
decoded as “pink”.
Thus option d) is correct.
6. If in certain language “oka peru” means “fine
cloth”, “meta lisa” means “clear water” and “don alias peru” means “fine clear
weather” .then which word in that language means “weather”.
a) Peru b) oka
c) meta d)don
Here
“oka peru” means “fine
cloth” 1
meta lisa” means “clear
water” 2
don lisa peru” means “fine clear
weather” 3
here weather is in third row , so find
weather we have to remove other option
i.e. fine clear therefore compare 3 AND
2 , 3 AND 1 to find common terms. thus we know that “fine” means “peru” and “clear” means “lisa”.Now eliminating
option we find that “weather” means “don”.
Thus option d)
is correct.
7.
If in certain language “123” means “bright little
boy”, “145” means “tall big boy” and “637” means “beautiful little flower”
.then which digit in that language means “bright”. [RRB 2004]
a) 1 b)2
c)3 d)4
Given that
“123” means “bright little
boy” 1
“145” means “tall big boy” 2
“637” means “beautiful little
flower” 3
Here “bright” is in 1 row. Therefore we have to eliminate other option
of 1 i.e “little boy”. For “boy” compare
1 and 2 to find common term then we will get “1”. For “little” compare 1 and 3
to find common term then we will get “3”. Thefore “bright” have 2.Now option 2 is correct.
