The reasoning section of every competitive exam is very crucial for an individual. This section can make or break the exam results for many students. There are many topics in the reasoning section and today we are going to cover one of those topics, Alphabetical Order. Generally, this topic covers adequate questions in the competitive exams and that is why it is a very important topic.
Table: Position of Alphabets From Left to Right
Table: Position of Alphabets From Right to Left
To memorise the position from left, the student should first learn the EJOTY Principle as explained here.
Each letter in the term EJOTY represents the position, which is a multiple of 5.
To solve questions based on alphabets, use the following rules:
To find the position of alphabet from L.H.S / R.H.S.
Directions (1-4): In the alphabet series we are given the position of an alphabet from L.H.S. What is the position of the alphabet from R.H.S.?Ex. 1: J is 10th alphabet from left.
Ex. 2: H is 8th alphabet from left.
Ex. 3: L is 12th alphabet from left.
Ex. 4: X is 24th alphabet from left.
Ans. 1: 27 – 10 = 17th from RHS.
Ans. 2: 27 – 8 = 19th from RHS.
Ans. 3: 27 – 12 = 15th from RHS.
Ans. 4: 27 – 24 = 3rd from RHS.
Similarly, if the position of an alphabet from right is known and we are required to find out its position from left, then just subtract the given position from 27 and we get the position of the alphabet from left.
T is 20th alphabet from left.
Directions (5-8): In the alphabet series we are given the position of an alphabet from R.H.S. What is the position of the alphabet from L.H.S.?Ex. 5: An alphabet is 14th from right.
Ex. 6: An alphabet is 2nd from right.
Ex. 7: An alphabet is 22nd from right.
Ex. 8: An alphabet is 9th from right.
Ans. 5: 27 – 14 = 13th from left.
Ans. 6: 27 – 2 = 25th from left.
Ans. 7: 27 – 22 = 5th from left.
Ans. 8: 27 – 9 = 18th from left.
An alphabet is 17th from right.
To find the opposite letter.
Following are some examples to find out the opposite alphabet:
Ex. 9: Opposite letter of D?
Ex. 10: Opposite letter of V?
Ex. 11: Opposite letter of J?
Ex. 12: Opposite letter of S?
Ans. 10: V is 22nd letter in the series from LHS. So its opposite letter is 27 – 22= 5 i.e. E
Ans. 11: J is the 10th letter in the series from LHS. So its opposite letter is 27 – 10 = 17 i.e. Q
Ans. 12: S is 19th letter in the series from LHS. So its opposite letter is 27 – 19 = 8 i.e. H
To find the middle position between the two alphabets.
There are three cases under Rule 3
When we are given the positions of the alphabets from left as well as from right in the alphabet series.
Following are the examples to find out the middle position of two alphabets:Ex. 13: 4th from right and 7th from left?
Ex. 14: 17th from left and 6th from right?
30/2 = 15 i.e. O
Ans. 14: We are required to find out the ‘middle’ letter between the 17th alphabet from left and the 6th alphabet from the right. The letter, which is 6th from right is 27-6= 21st from left. Adding both the left hand side positions, we get 17+21=38 and when we divide 38 by 2, the answer is 19.
38/2 = 19 i.e. S
Which letter will be the midway between the fourteenth letter from the left end and nineteenth letter from the right end of the following alphabet ?
When we are given only two alphabets.
Following are the examples to find out the middle position of two alphabets in this case:
Ex. 15: Which is the middle letter between H and N?
Ans:
22/2 = 11 i.e. K
Ex. 16: Which is the middle letter between H and T?
28/2 = 14 i.e. N
When we are given the position of two alphabets from R.H.S.
Ex. 17: 10th from right and 4th from right
Relative position between the two alphabets.
General Pattern: Which alphabet is – to the left/ right of – from left/ right
So for this, we can make the following as the general rule:
Following are some of the examples:
Ex. 18: Which alphabet is 8th to right of 10th from left?
Ex. 19: Which alphabet is 4th to left of 20th from right?
Ans. 18: One position is from left and the other is from the right. So according to the above table:
8 + 10 = 18th from left i.e. R
Ans. 19: One position is from left and the other is from the right. So according to the above table:
4 + 20 = 24th from right = 3rd from left (27 – 24) i.e. C.
Arrangement of letters in alphabetical order and finding out the position from left or right.
Following are some of the examples:
Ex. 20: If the word PENCIL is written alphabetically then which is the fourth letter from right?
Ex. 21: If the word COUNTER is written alphabetically then which is the third letter from left?
Ex. 22: If the word REPRESENTATION is written alphabetically then which is the second word to the left of fifth from right?
Ans. 20: PENCIL word when broken down can be written as CEILNP. So the fourth alphabet from right is I.
Ans. 21: The said letter after it is written in alphabetical order is: CENORTU. So the third letter from left is N.
Ans. 22: The said word after it is written in alphabetical order is: AEEEINNOPRRSTT. The second word to left of fifth from right is 5th + 2nd = 7th from right i.e. O.
Arrangement of words in alphabetical order.
Ex. 23: Arrange the following words in alphabetical order or as per the dictionary.
(a) Plight
(b) Pledge
(c) Pugilist
(d) PanderThe correct answer is (i) Pander (ii) Pledge (iii) Plight (iv) Pugilist
Ex. 24: Arrange the following words in alphabetical order or as per the dictionary.
(a) sundry
(b) script
(c) season
(d) slightThe correct answer is (i) Script (ii) Season (iii) slight (iv) Sundry
