Here you can check out the new pattern Coding-Decoding Problems with the explanation. You can also check the same pattern of some important problems which are asked in various bank exams.

Example – 1:

In a certain code,
“RING MONEY BAN JAR” is written as ‘24#G, 7%Y, 16\$N, 12@R’
“JAM ROUND BAT MONDAY” is written as ‘17@M, 28#D, 10\$T, 8%Y’
“MOUNTAIN BEAR RANDOM JUMP” is written as ‘21%N, 13\$R, 20#M, 15@P’
“RADIO JOKE BANGLE MUD” is written as ‘17#O, 26@E, 28\$E, 26%D’

The code for “RUN” is

RUN – 16#N
R – #
No of letters – 3+(Reverse Alphabet order of N = 13) = 16
Last letter – N

Identify the symbols with the help of the last letter of the word.

• Letter starts with R – Ring, Round, Random and Radio – #
• Letter starts with M – Mountain, Mud, Monday and Money – %
• Letter starts with J – Joke, Jump, Jam and Jar  – \$
• Letter starts with B – Bat, Ban, Bear and Bangle – @

• First Position is coded with Number -> No of letters +(Reverse Alphabet order of the last letter)
• Second Position – Symbol
• Third Position – Last letter of word

Example – 2:

In a certain code language,
‘CAT DONKEY FAN EARTH’ is written as “*1@7, !1&9, ~1@1, #0%3”
‘COW DULL FOREST ELBOW’ is written as “*2@0, #1%8, !0^8, ~1&4”
‘CAN DOORS FOUR ELEVEN’ is written as “~1^4, !1%4, *1@1, #0&8”
‘FAMILY CAR EAGER EGG’ is written as “#0@4, *1@5, ~1&9, #1%3”

code for “FAMILY”

First Position – symbol denotes first letter = (F-~)
Third Position – symbol denotes total number of words = (6 letter word – &)
Second & Fourth position = Alphabet order of last letter – Number of letters = (25 – 6) = 19; Second position – 1; Fourth position – 9.
