Tricks for Alphabet Set
This type of question vary on the arrangement of alphabetical order. It can be Backward, first half backward, second half backward, multiple letter segments in changed order etc. Some of the question asked are based on finding the middle letter of two specified letters and in some questions it is asked that which letters do not change their place after alphabet arrangement.
So, the detailed explanation with examples is as follow:
1. Place of letter in forward order
In this type of questions the exact letter has to be found out with the help of direction of place given in the question. The example discussed as below will give you a better idea about this type of questions.
Ex 1: Find the 11th letter to the left of 20th letter from left in the English alphabet.
Let us see
Hence, 11th letter to the left of 20th letter from left is I.
In English alphabet 11th letter to the left of 20th letter of your left =(20-11) th letter from the left=9th letter from the left =I
2. Place Of Letter in Completely Backward Order
In such questions the order of letters is completely reversed or they are counted from Z to A and then the place of letter is asked with the help of direction.
Ex 2: If English alphabet is written in backward order, then what will be 13th letter to the left of the 3rd letter from right?
Backward order is written as
Now, the 13th letter to left of the 3rd letter from right is P.
In backward order of alphabet,13th letter to the left of the 3rd letter of your right =(3+13)th letter from right =16th letter from right P.
3. Place of a Letter When First Half is in Backward Order
In such type of question, only the 1st half of the order of alphabetical series is reversed and remaining are left unaltered i.e., order of A to M is reversed and then questions related to position of latter are asked.
Ex 3: If 1st half of the English alphabet is written in backward order, then what will be the 7th letter to the left the 10th letter from your right?
Let us see
The 7th letter to the left of 10th letter from our right is D.
4. Place of a Letter When Second Half is in Backward Order
In such type of questions the 2nd half is reversed i.e., from N to Z and remaining are kept as it is and then questions related to place of English alphabet are asked.
Ex 4: If 2nd half of the English alphabet is written in backward order, then what will be the 7th letter to the right of 13th letter from your left?
Let us see
The 7th letter to the right of 13th letter from our left is T.
5. Multiple Letter Segment in Backward Order
In such type of questions, no specified order of change is followed in alphabetical order. The are changed according to the condition given in particular question.
Ex 5: If first four letters of the English alphabet are written in reverse order; again next 5 letters are written in reverse order ;again next 6 letter s are written in reverse order ; next 7 letter are written in reverse order and finally, the remaining letters are also written in reverse order, then what will be the 7th letter to the left of the 8th letter from right?
Let us see the arrangement
The 7th letter to the 8thth letter from right is M.
6. Number of Letter in the Middle of Two Letters
In this particular type, question asked to calculated the total number of English letters between any two specified letter as directed in the question.
Four situations can be created under these type of problems
Ex 6: How many letters are there between 8th letter from left and 7th letter right in the English alphabet?
Let us see
There are 11th letters between 8th letter from left and 7th letter from right.
Total number of letter in the English alphabet =26
Required number of letters =26-(8+7) =11
7. Middle Letter between Two letters
In these types of questions, it is asked to find the middle letter the two specified letters of English alphabet.
Ex 7: Which letter is in the middle of 7th letter from left and 10th letter from right in the English alphabet?
Let us see
Letters between G and Q is L.
10th letter from right =27-10 =17th letter from left.
Required middle letter =7+(17-7)/2 =24/2 =12th letter from left =L
8. Same Position of Alphabet after Arranging Alphabetically
In this type of questions, a word is given and then asked how many letters remain same in their position, if they are arranged in alphabetical order.
Ex 8: How many such letters are there in the word ‘CADMP’ which remain same in their position, if they are arranged in alphabetical order?
