Question 1

In the English alphabet, if every alternate letter starting from B is replaced by its position number (i.e., B→2, D→4, F→6, ... and so on), then what will be the sum of all the numbers that replace the letters between the 10th and 20th positions of the original alphabet (both exclusive)?

Accepted Answer

Step 1: Identify letters at positions 10 to 20 in the English alphabet.
Positions 1–26: A=1, B=2, C=3, D=4, E=5, F=6, G=7, H=8, I=9, J=10, K=11, L=12, M=13, N=14, O=15, P=16, Q=17, R=18, S=19, T=20, U=21...

Step 2: Letters BETWEEN 10th (J) and 20th (T) positions, both exclusive, are:
K(11), L(12), M(13), N(14), O(15), P(16), Q(17), R(18), S(19)

Step 3: The rule states every alternate letter starting from B is replaced by its position number. So B(2), D(4), F(6), H(8), J(10), L(12), N(14), P(16), R(18), T(20) are replaced. These are all EVEN-positioned letters.

Step 4: Among K(11), L(12), M(13), N(14), O(15), P(16), Q(17), R(18), S(19), identify which are even-positioned:
L=12 → replaced by 12
N=14 → replaced by 14
P=16 → replaced by 16
R=18 → replaced by 18

Step 5: Sum of replaced numbers = 12 + 14 + 16 + 18 = 60

Common mistake (Option A - 90): Candidates may include J and T (boundary positions) by not reading 'exclusive'.
Common mistake (Option C - 48): Candidates may only pick L and R (every 4th alternate), missing N and P.
Common mistake (Option D - 72): Candidates may add position numbers of odd-lettered ones (11+13+15+17+19=75, or miscalculate as 72).

Question 2

If the letters of the English alphabet are written in reverse order (Z, Y, X, ..., B, A), which letter will be the 7th from the left?

Accepted Answer

In reverse alphabetical order: Z(1), Y(2), X(3), W(4), V(5), U(6), T(7). The 7th letter from the left is T.

Question 3

If you reverse the English alphabet (Z=1, Y=2, X=3, ... A=26), what is the position of the letter 'T'?

Accepted Answer

In the reversed alphabet, Z=1, Y=2, X=3, ... T is the 7th letter from the end. Counting backward: Z(1), Y(2), X(3), W(4), V(5), U(6), T(7). So T=7 in the reversed system.

Question 4

In the English alphabet, how many letters are there between M and V (excluding both M and V)?

Accepted Answer

M is the 13th letter and V is the 22nd letter. Letters between them: N(14), O(15), P(16), Q(17), R(18), S(19), T(20), U(21). That is 8 letters.

Question 5

Starting from A and moving forward, if you skip every 2nd letter, which letter will you land on at the 4th stop?

Accepted Answer

Start at A. Skip B, land on C (1st stop). Skip D, land on E (2nd stop). Skip F, land on G (3rd stop). Skip H, land on I (4th stop). The answer is I.

Question 6

If the letters of the English alphabet are numbered from 1 to 26 (A=1, B=2, C=3, ... Z=26), what is the position of the letter 'M'?

Accepted Answer

The letter M is the 13th letter in the English alphabet. Counting from A(1) to M: A=1, B=2, C=3, D=4, E=5, F=6, G=7, H=8, I=9, J=10, K=11, L=12, M=13.

Question 7

If you count from the right side of the alphabet, which letter is at the 5th position?

Accepted Answer

Counting from right: Z(1), Y(2), X(3), W(4), V(5). The 5th letter from the right is V.

Question 8

How many letters are there between 'D' and 'H' in the English alphabet?

Accepted Answer

D is at position 4 and H is at position 8. The letters between them are E(5), F(6), G(7). That is 3 letters between D and H (not counting D and H themselves).

Question 9

Which letter is 5 positions to the right of 'J' in the English alphabet?

Accepted Answer

J is at position 10. Moving 5 positions to the right: J(10) → K(11) → L(12) → M(13) → N(14) → O(15). The answer is O.

Question 10

In the English alphabet, which letter comes exactly in the middle between 'G' and 'M'?

Accepted Answer

G is at position 7 and M is at position 13. The middle position is (7 + 13) ÷ 2 = 20 ÷ 2 = 10. Position 10 is J.

Question 11

How many letters in the English alphabet are there between the 5th letter from the left and the 5th letter from the right (not including these two letters)?

Accepted Answer

The 5th letter from the left is E (A=1, B=2, C=3, D=4, E=5). The 5th letter from the right is V (Z=1, Y=2, X=3, W=4, V=5). Between E and V, the letters are F, G, H, I, J, K, L, M, N, O, P, Q, R, S, T, U. That is 16 letters.

Question 12

If we assign numerical values to letters (A=1, B=2, C=3, ... Z=26), and we form a new sequence by taking alternate letters starting from B (B, D, F, H, ...), what is the sum of the numerical values of the 8th and 12th letters in this new sequence?

Accepted Answer

Alternate letters starting from B: B(2), D(4), F(6), H(8), J(10), L(12), N(14), P(16), R(18), T(20), V(22), X(24). The 8th letter is P(16), the 12th letter is X(24). Sum = 16 + 24 = 40.

Question 13

In a row of letters arranged as: 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, if every 3rd letter starting from A is removed, which letter will be at the 15th position in the remaining sequence?

Accepted Answer

Original: 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. Remove every 3rd: Remove C, F, I, L, O, R, U, X. Remaining: A B D E G H J K M N P Q S T V W Y Z (18 letters). The 15th letter in this sequence is W.

Question 14

If the letters of the English alphabet are written in reverse order (Z, Y, X, ..., B, A), then which letter will be the 7th letter to the right of the 10th letter from the left in this reversed sequence?

Accepted Answer

In the reversed alphabet sequence (Z=1, Y=2, X=3, ..., B=25, A=26), the 10th letter from the left is Q. The 7th letter to the right of Q means moving 7 positions forward in the reversed sequence: Q(10) → P(11) → O(12) → N(13) → M(14) → L(15) → K(16). Therefore, the answer is K.

Question 15

In the alphabet, if every alternate letter starting from B is removed (i.e., B, D, F, H, J, L, N, P, R, T, V, X, Z are removed), how many letters remain?

Accepted Answer

The alphabet has 26 letters. The letters to be removed are B, D, F, H, J, L, N, P, R, T, V, X, Z (every alternate letter starting from B). That is 13 letters. Remaining letters = 26 - 13 = 13 letters (A, C, E, G, I, K, M, O, Q, S, U, W, Y).

Question 16

If you write the alphabet twice consecutively (ABCDEFGHIJKLMNOPQRSTUVWXYZABCDEFGHIJKLMNOPQRSTUVWXYZ), what is the 45th letter in this sequence?

Accepted Answer

The sequence is the alphabet written twice. The first 26 letters are A-Z (positions 1-26). The next 26 letters are A-Z again (positions 27-52). Position 45 falls in the second repetition. Position 45 = 26 + 19, so it is the 19th letter of the second alphabet, which is S.

Question 17

In the English alphabet, if we count 5 positions forward from M, then 3 positions backward from that letter, and then 4 positions forward again, which letter do we reach?

Accepted Answer

Start at M (13th letter). Move 5 forward: M→N→O→P→Q→R (18th letter = R). Move 3 backward: R→Q→P→O (15th letter = O). Move 4 forward: O→P→Q→R→S (19th letter = S). Final letter = S.

Question 18

In a certain code, each letter is replaced by the letter that comes 3 positions after it in the alphabet (with Z wrapping to C, Y to B, X to A). If the word 'ZEBRA' is coded using this rule, what is the coded word?

Accepted Answer

Using the +3 shift rule with wrapping: Z→C (Z is 26th, +3 wraps to 3rd=C), E→H, B→E, R→U, A→D. The coded word is CHEUD.

Question 19

In a sequence where every 3rd letter of the alphabet is selected (C, F, I, L, O, R, U, X), and then these selected letters are arranged in reverse order, what is the position of letter O in the original alphabet among only the selected letters?

Accepted Answer

Tests the ability to identify elements based on a selection rule, reverse the selection, and find the position of a specific element in the modified sequence.

Question 20

In a certain code, letters are arranged based on their position in the English alphabet. If we reverse the alphabet (Z=1, Y=2, X=3, ... A=26) and then add the position number of each letter in the word REASONING, what is the sum of the values for letters R, E, and G only?

Accepted Answer

This question tests the ability to work with reverse alphabet coding and selective summation without mixing forward and reverse positions.

Question 21

If every alternate letter starting from B in the English alphabet is removed, and then the remaining letters are numbered from 1 onwards, what is the position of the letter M in this new sequence?

Accepted Answer

Tests the ability to identify which letters remain after a systematic removal pattern and then find the position of a specific letter in the modified sequence.
