In competitive tests, the reasoning component is the most crucial.
Alpha-Numeric series is a common type of logic inquiry.
This section's questions are typically simple and highly gradeable.
Any competitive exam will almost certainly have one to four questions from this area.
The following sorts of series are the basis for the questions:If you are preparing for competitive exams and looking for expert guidance, you can download our General Knowledge Free Ebook **Download Now.**

Missing Series:**2. Alphabet-Number-Symbol:**These questions may also be asked in a format where a series with alphabets, number and different types of symbols (like &, *, $, etc.) may be given, and questions may be asked based on them

**3.Only Alphabetic Series:**Series with either missing element or questions with sub-parts may be asked which comprise only English Alphabets and no numbers, set in a specific pattern

**4.Only Numerical Series:**Series comprising only numbers, set in a specific pattern may be asked the exam. Questions based on this type may be asked in the form of rearrangement of numbers or digits with the number in ascending, descending or any other order.

Solution 11:

According to the given series -

8 K L 5 I R T 8 2 % U * 1 S V ^ W N M Z 2 7 $ F ! B ¥ 0

After deleting all the odd numbers then series will be 8 K l R T 8 2 % U * S V ^ W N Z 2 $ F ! B ¥ 0 And the 8th element the right end is Z.

Solution 12:

According to the given series -

8 K L 5 I R T 8 2 % U * 1 S V ^ W N M Z 2 7 $ F ! B ¥ 0

After eliminating all the alphabets then the series will be

8 5 8 2 % * 1 ^ 2 7 $ ! ¥ 0

And the 10th element from the left side is 7.

Solution 13:

According to the given series -

8 K L 5 I R T 8 2 % U * 1 S V ^ W N M Z 2 7 $ F ! B ¥ 0 Addition of all the numbers of the given series is 33. (8+5+8+2+1+2+7+0)

Solution 14: According to the given series - 8 K L 5 I R T 8 2 % U * 1 S V ^ W N M Z 2 7 $ F ! B ¥ 0 And after the digits in the series are multiplied with 3,resultant is 99 (8*3+5*3+8*3+2*3+1*3+2*3+7*3+0*3). Solution 15:

According to the given series -

8 K L 5 I R T 8 2 % U * 1 S V ^ W N M Z 2 7 $ F ! B ¥ 0

After eliminating all the symbols series will be

8 K L 5 I R T 8 2 U 1 S V W N M Z 7 F B 0

And the 3rd element to the right of the 5th element from the left side is 8.

Solution 16:

According to the given series -

R % 4 ! C 7 B 1 ^ N 3 π C F © 8 S Ω 9 L Q X & G £ D & R 3 * O

After dropping all the consonants series will be

% 4 ! 7 1 ^ 3 π © 8 Ω 9 & £ & 3 * O

And the 6th from the right of the 2nd element from the left end is π.

Solution 17:

According to the given series -

% 4 ! C 7 B 1 ^ N 3 π C F © 8 S Ω 9 L Q X & G £ D & R 3 * O

And total symbols followed by an alphabet and preceded by a number is 4.

( 4 ! C 1 ^ N 3 π C 3 * O)

Solution 18:

According to the given series -

R % 4 ! C 7 B 1 ^ N 3 π C F © 8 S Ω 9 L Q X & G £ D & R 3 * O

After reversing the series from right end -

O * 3 R & D £ G & X Q L 9 Ω S 8 © F C π 3 N ^ 1 B 7 C ! 4 % R

And the difference between the number 6th right end and 13th from left end is 9 – 7 = 2

Solution 19:

According to the given series -

R % 4 ! C 7 B 1 ^ N 3 π C F © 8 S Ω 9 L Q X & G £ D & R 3 * O

And the sum of place value according to alphabet series of the element in given series 7th from left end and 8th from right end is 2 + 7 = 9.(as B=2 ; G= 7)

Solution 20:

According to the given series -

R % 4 ! C 7 B 1 ^ N 3 π C F © 8 S Ω 9 L Q X & G £ D & R 3 * O And the symbols between B and D is 6.

We hope these important alpha numeric series questions and answers helped students gain an insight into the type of questions that constitute Alpha Numeric Series in Reasoning Section. Students may find series section a bit complex in the beginning, regular practice will ensure you are comfortable with the series.
