Alphanumeric Series -How to solve these questions easily?

Alphanumeric Series

Alphanumeric series is a combination of alphabets, numbers, and symbols. It is a sequence that consists of both numbers and alphabets. This topic is very important because you can expect 3-5 questions from this topic. We will give proper attention to this topic and will solve easy, moderate, and difficult category questions.

Some important points to remember

  • Vowels – A,E.I,O and U.
  • Consonants – All letters except vowels.
  • Numbers – 1,2,3,4,5,6,7,8,9 etc.
  • Symbols – &,*,#,@,% etc
  • p is preceded by q means q will be left to p.
  • P is followed by q means q will be right to p.
  • If both numbers are in same direction like left + left then Subtract.
  • Both numbers are in opposite direction like right + left then Add.
There can be four types of questions that cab be asked.
  • Number Series
  • Alphabet series
  • Alphanumeric series
  • Alphanumeric symbol series
Alphanumeric Series

Number Series

We will solve a question based on this type. Please give proper attention to this topic.
  1. Study these five 3 digit numbers and solve these questions carefully:

374 659 821 945 247

  • if 2 is subtracted from the last digit of each number, how many numbers thus formed is divisible by 3?
    • Firstly subtract 2 from the last digits and write the new numbers formed: 371 656 818 942 244
    • Now if you know the divisibility rule then you can solve this very easily ( click here to learn divisibility) otherwise you can manually check divisibility.
    • In this case, only one number is divisible by 3, so our answer is 1.
  • If in each number the first and third digits are interchanged, which of the following will be second-highest?
    • Firstly, interchange first and third digit in all numbers and write down new numbers: 473 956 128 249 442
    • Now you can easily find the second-highest numbers: 374
  • If in each number 3 is added to the 2nd digit and the last 2 digits are interchanged then which will be the lowest?
    • Add 3 to the 2nd digit first and write down new number formed: 404 689 851 975 277
    • Now interchange last 2 digits and write a new number: 440 698 815 757 277
    • Now you can find lowest number easily: 247

Alphabetic series

  1. Study the following alphabet series and solve these questions carefully:

LAP BUT CAR SON ONT

  • If the position of the first and the third alphabets of each word are interchanged, which of the word would form the meaningful word?
    • Change the position of first and 3rd alphabet of each word and write down new words thus formed: PAL TUB RAC NOS TON
    • Now check the meaningful words formed as in this case there are two meaningful words formed: TUB TON
    • In this case, the answer is BUT ONT
  • If the second alphabet in each word is changed to the next alphabet, how many words having no vowels will be formed?
    • Change the third alphabet to the next alphabet according to English alphabetic series and write down the new words formed: LBP BVT CBR SPN OOT
    • Now check the vowels list and with that list, you can easily find out the word having no vowel
    • In this case, we have 4 words which have no vowel: LBP BVT CBR SPN
  • If the given words are arranged in the order as they would appear in the English dictionary from left to right which of the following will be third from left?
    • Arrange the words according to English dictionary and write down new words formed: BUT CAR LAP ONT SON
    • Now find the word which is third from the left: LAP

Alphanumeric Series

Alphanumeric series
  1. Study the following alphanumeric series and solve these questions carefully:

A 8 9 I F G 8 0 A 7 5 B 6 C 9 D 5 Y Z

  • How many such consonants are there in the above sequence which are both immediately preceded by and followed by a number?
    • Firstly you should know what is preceded by, followed by, and consonants.
    • Now check the consonant which looks like 1B1.
    • In the given arrangement we have 3 pairs which are immediately preceded by and followed by a number: 5B6 6C9 9D5
  • After dropping all the numbers, Which letter will be Third to the left of the fifth letter from the right end?
    • Write down all the alphabets: A I F G A B C D Y Z
    • Now according to rule Left+Right is subjected to addition (3+5=8, this means we have to find 8th alphabet from the right end)
    • The required answer is: F
  • How many such alphabets are in an above sequence which is followed by an alphabet and preceded by a number?
    • Check the alphabets which look like 1AB.
    • In the above arrangement, we have 2 pairs which are followed by an alphabet and preceded by a number: 9IF 5YZ

Alphanumeric Symbol sequence series

  1. These questions are based on the following arrangement of letters, numbers, and symbols. Study them carefully and answer the following questions based on this concept:

K 2 8 % A & B 3 H $ G T 1 V Y W @ % 6 9 ! L V H

  • If all the symbols are dropped from the above arrangement, which of the following will be 6th from the right end?
    • Remove all symbols and write down new-formed arrangement: K 2 8 A B 3 H G T 1 V Y W 6 9 L V
    • Now find out the 6th number/alphabet from the right end: Y
  • How many such consonants are there in the above arrangement which is not immediately preceded by a symbol?
    • Find out the consonants which don’t look like @B
    • In this case, we have 8 consonants which is not immediately preceded by a symbol: K 3H GT 1V VY YW LV VH
  • If all the alphabets in the above arrangement are arranged in English alphabetical order, which of the following will be 11th from the left?
    • Arrange the Alphabets according to English alphabetic order: A 2 8 % B & G 3 H $ H K 1 L T V @ % 6 9 ! V W Y
    • 11th alphabet from the left according to new arrangement formed: H

This is the most important topic and we have used an easy , moderate, and difficult example to solve this topic. Now you can solve the questions based on this approach and if you need any help then do mail me on [email protected]
