Rajat patel answered
Solution:

First, we need to find the letter which is fourth to the left of I.

Counting four letters to the left of I, we get the letter E.

Now, we need to find the letter which is 16th to the right of E.

Starting from E, we count 16 letters to the right.

The letter that we reach is U.

Therefore, the letter which is 16th to the right of the letter which is fourth to the left of I is U.

Therefore, option (c) is the correct answer.

Mythili garg answered
Solution:

To find the sixth letter to the left of the 19th letter from the right end of the alphabet, we need to first find the 19th letter from the right end of the alphabet.

There are 26 letters in the English alphabet, so the 19th letter from the right end of the alphabet can be found by subtracting 18 from 26, which gives us the 8th letter from the beginning of the alphabet.

So, the 19th letter from the right end of the alphabet is "H".

To find the sixth letter to the left of "H", we count six letters to the left of "H", which gives us the letter "B".

Therefore, the answer is option E, None of these, as none of the given options match with the letter "B".

If the first half of the English alphabet is reversed and then next portion of English alphabet is reversed so as 'A' takes the portion of 'M' and 'N' takes the portion of 'z' then which letter will be 6th to the left of 17th letter to the right of 7th leter from the left?
  • a)
     U
  • b)
     V
  • c)
     C
  • d)
     D
Correct answer is option 'B'. Can you explain this answer?

Dia Mehta answered
6th to the left of 17th letter to the right of 7th letter from the left = 6th to the left of (17+7 =) 24th letter from the left = (24-6 =) 18th letter from the left.
Thus, we have to count from the left and we have to find out 18th letter from the left that falls into the second section of English alphabet.
Here, both the first half and the second half of the English alphabet have been reversed and we have to count from the left end, then the required letter can be found out using the formula given below. Suppose, the first and the second reversed sections of the English alphabet are α and  β respectively.Then,
The required letter = 2α+β+1−(required position of letter from left side)
Therefore, The required letter = 26 + 13 + 1 - 18 = 22 = V

    K              
  • b)
    O
  • c)
    P              
  • d)
    R
  • e)
    None of these
Correct answer is option 'C'. Can you explain this answer?

Sandeep Chavan answered
Solution:

To find the seventh letter to the right of the eighteenth letter from the right end of the alphabet, we need to follow the given steps:

Step 1: Count the total number of letters in the English alphabet, which is 26.

Step 2: Count the 18th letter from the right end of the alphabet, which is G.

Step 3: Count seven letters to the right of G, which gives us the letter P.

Therefore, the seventh letter to the right of the eighteenth letter from the right end of the alphabet is P.

Hence, option (c) is the correct answer.

Tulika Menon answered
Solution:

The given alphabet series is: A B C D E F G H I J K L M N O P Q R S T U V W X Y Z

From the left end, the thirteenth letter is M.

To find the seventh letter to the right of M, we need to count seven letters to the right of M.

Counting seven letters to the right of M, we get the letter T.

Hence, the correct answer is option (B) T.

Note: It is important to pay close attention to the instructions given in the question. In this case, we are asked to find the seventh letter to the right of the thirteenth letter from the left end.

In a certain code 'PENCIL' is written as 'RCTAMJ' then in that code 'BROKEN' is written as :
  • a)
     SPFLIM
  • b)
     SVFLIN
  • c)
     FVSMGL
  • d)
     FPSMIL
  • e)
     None of these
Correct answer is option 'E'. Can you explain this answer?

Dia Mehta answered
The first three letters of the word are reversed. Thus PENCIL becomes NEPCIL. Now add 4 to odd-positioned letters and subtract 2 from even-positioned ones.
Similarly, BROKEN becomes ORBKEN.
Then we do the calculations: O +4, R -2, B +4, K -2, E +4, N -2
Resulting word = SPFIIL

Q.Which of the following is the twelfth letter to the left of the seventeenth letter from the left end?
  • a)
    E              
  • b)
    F
  • c)
    G              
  • d)
    T
  • e)
    None of these
Correct answer is option 'A'. Can you explain this answer?

Solution:

To find the twelfth letter to the left of the seventeenth letter from the left end, we need to follow these steps:

Step 1: Find the seventeenth letter from the left end
The seventeenth letter from the left end is Q.

Step 2: Count twelve letters to the left of Q
Counting twelve letters to the left of Q, we get E.

Therefore, the twelfth letter to the left of the seventeenth letter from the left end is E.

Answer: (a) E

  • b)
    Two          
  • c)
    Three

Bhavna Kapoor answered
Understanding the Problem
The task is to find pairs of letters in the word "CORPORATE" such that the number of letters between them in the word matches the number of letters between them in the English alphabet.
Steps to Solve
1. Identify the Letters:
The letters in "CORPORATE" are: C, O, R, P, O, R, A, T, E.
2. Check Each Pair:
We'll compare each letter with every other letter that comes after it and see if the distance between them in the word matches the distance in the alphabet.
Pairs of Letters
- C and O:
- In the word: 1 letter (R) between C and O.
- In the alphabet: C(3) to O(15) = 15 - 3 - 1 = 11 (not a match).
- C and R:
- In the word: 2 letters (O, R) between C and R.
- In the alphabet: C(3) to R(18) = 18 - 3 - 1 = 14 (not a match).
- C and A:
- In the word: 5 letters (O, R, P, O, R) between C and A.
- In the alphabet: C(3) to A(1) = 1 + 26 - 3 - 1 = 23 (not a match).
- C and T:
- In the word: 6 letters (O, R, P, O, R, A) between C and T.
- In the alphabet: C(3) to T(20) = 20 - 3 - 1 = 16 (not a match).
- O and R:
- In the word: 0 letters between O and R.
- In the alphabet: O(15) to R(18) = 3 - 1 = 2 (not a match).
- O and A:
- In the word: 5 letters between O and A.
- In the alphabet: O(15) to A(1) = 1 + 26 - 15 - 1 = 11 (not a match).
- R and P:
- In the word: 0 letters between R and P.
- In the alphabet: R(18) to P(16) = 2 - 1 = 1 (not a match).
- A and T:
- In the word: 0 letters between A and T.
- In the alphabet: A(1) to T(20) = 20 - 1 - 1 = 18 (not a match).
Identified Pairs
The pairs that match the criteria are:
1. (C, R): 2 letters between them in the word and 14 in the alphabet.
2. (O, A): 5 letters between them in the word and 11 in the alphabet.
3. (R, E): 2 letters between them in the word and 2 in the alphabet.
Thus, the correct answer is
