NUMBER CODING
In this type of questions, words are coded by digits. We have to decode based on common letters
Example- 01: In a certain code, ENTRY is written as 12345 and STEADY is written as 931785 then how is TENANT written in that code?
Solution:
E N T R Y
1 2 3 4 5
S T E A D Y
9 3 1 7 8 5
Similarly,
T E N A N T
3 1 2 7 2 3
Example- 02:
In a certain code, BOWLER is written as 613972 and WINE is written as 3457 then how is IRON written in that code?
Solution:
B O W L E R
6 1 3 9 7 2
W I N E
3 4 5 7
Similarly,
I R 0 N
4 2 1 5
Example- 03:
If D = 4, COVER = 63 then BASIS =?
Solution:
In English alphabet position value of D = 4 Similarly
C = 3, 0 = 15, V= 22, E = 5, R = 18. If we observer sum of these values is 63. According to this logic BASIS= 2 +1+ 19 + 9+19= 50
SYMBOL CODING
Example- 04:
In a certain code BEND is written as ‘#$?&I’ and RAIN is written as ‘@*%?.. How is DARE written in that code?
Solution:
B E N D
# $ ? &
R A I N
@ * % ?
Similarly,
D A R E
& * S $
Example- 05:
In a certain code TEAM is written as ‘?8p?’ and FLEW is written as ‘@*8&’. How is MELT written in that code?
Solution:
T E A M
? 8 P ?
F L E W
@ * 8 &
Similarly,
M E L T
? 8 * ?
