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 (14): 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 10^{th} alphabet from left.
Ex. 2: H is 8^{th} alphabet from left.
Ex. 3: L is 12^{th} alphabet from left.
Ex. 4: X is 24^{th} alphabet from left.
Ans. 1: 27 – 10 = 17^{th} from RHS.
Ans. 2: 27 – 8 = 19^{th} from RHS.
Ans. 3: 27 – 12 = 15^{th} from RHS.
Ans. 4: 27 – 24 = 3^{rd} 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.
Directions (58): 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 14^{th} from right.
Ex. 6: An alphabet is 2^{nd} from right.
Ex. 7: An alphabet is 22^{nd} from right.
Ex. 8: An alphabet is 9^{th} from right.
Ans. 5: 27 – 14 = 13^{th} from left.
Ans. 6: 27 – 2 = 25^{th} from left.
Ans. 7: 27 – 22 = 5^{th} from left.
Ans. 8: 27 – 9 = 18^{th} from left.
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 22^{nd} letter in the series from LHS. So its opposite letter is 27 – 22= 5 i.e. E
Ans. 11: J is the 10^{th} letter in the series from LHS. So its opposite letter is 27 – 10 = 17 i.e. Q
Ans. 12: S is 19^{th} 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: 4^{th} from right and 7^{th} from left?
Ex. 14: 17^{th} from left and 6^{th} 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 276= 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
14^{th} from the right and 19^{th} from the left?++
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: 10^{th} from right and 4^{th} 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 8^{th} to right of 10^{th }from left?
Ex. 19: Which alphabet is 4^{th} to left of 20^{th} from right?
Ans. 18: One position is from left and the other is from the right. So according to the above table:
8 + 10 = 18^{th} 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 = 24^{th} from right = 3^{rd} 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 5^{th} + 2^{nd} = 7^{th} 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
