Amrita choudhary answered
Given series: Z, U, Q, ?, L

To find: Missing term in the series

Observations:

- The series is a combination of letters in reverse alphabetical order.
- The letters are placed at an interval of 4 positions from each other.

Method:

- We can find the missing term in the series by following the same pattern.
- Starting from L, we need to add 4 positions to it to get the next term.
- We repeat the process until we get the missing term.

Calculation:

- Starting from L, adding 4 positions, we get H.
- Adding 4 positions to H, we get D.

Therefore, the missing term in the series is D.

Hence, the correct answer is option (d) D.

Pallavi khanna answered
The given letter series is U, O, I, ?, A. We need to find the missing term.

Pattern:
When we look at the given series, we can observe the following pattern:
- The series is a combination of vowels and consonants.
- The vowels are placed alternatively in descending order of their alphabetical position.
- The consonants are placed alternatively in ascending order of their alphabetical position.

Using this pattern, we can find the missing term.

Solution:
- The first vowel in the series is U, which is the 21st letter of the English alphabet.
- The next vowel should be placed two positions before U in the alphabet.
- Therefore, the next vowel should be S, which is the 19th letter of the alphabet.
- The first consonant in the series is O, which is the 15th letter of the alphabet.
- The next consonant should be placed two positions after O in the alphabet.
- Therefore, the next consonant should be Q, which is the 17th letter of the alphabet.
- The next vowel should be placed two positions before S in the alphabet.
- Therefore, the missing term should be E, which is the 5th letter of the alphabet.
- The last letter in the series is A, which is the 1st letter of the alphabet.

Therefore, the missing term in the series is E, which is option (a).

  • d)
    O, Q   
Correct answer is option 'A'. Can you explain this answer?

Kiran Reddy answered
The first, fourth and seventh letters are in alphabetical order. So, tenth letter would be the letter after C i.e. D.
Also the second and third letter are alternate and in reverse order and so are the fifth and sixth letters and the eighth and ninth letters.

If the fourth, the fifth, the fourteenth, the fifteenth and the twenty-sixth letters of the English alphabet are so rearranged as to form one meaningful English word taking each letter only once, what will be the middle letter of that word? If more than one such word are formed, your answer should be K and if no such word can be formed your answer would be Y.
  • a)
    N                                
  • b)
    Z
  • c)
    O                                
  • d)

Given information: The fourth, the fifth, the fourteenth, the fifteenth and the twenty-sixth letters of the English alphabet are to be rearranged to form one meaningful English word taking each letter only once.

To find: The middle letter of the word formed.

Approach:

- Identify the letters that need to be rearranged.
- Find all possible combinations of those letters.
- Check if any of those combinations form a meaningful English word.
- If more than one word is formed, the middle letter of each word should be checked.
- If no word is formed, the answer is Y.

Solution:

The letters that need to be rearranged are D, E, N, O, and Y.

All possible combinations of these letters are:

- DENOY
- DENOY
- DEONY
- DEOYN
- DEONY
- DEOYN
- DNYOE
- DNYOE
- DNOYE
- DNOEY
- DNEYO
- DNEOY
- DYNEO

EduRev SSC CGL answered
We can break it down by observing the pattern in each letter:
  1. First letters (s, r, q, p, ?):
    • s (19th letter) to r (18th letter): -1 position
    • r (18th letter) to q (17th letter): -1 position
    • q (17th letter) to p (16th letter): -1 position
    • Continuing the pattern, p (16th letter) to the next letter would be o (15th letter).
  2. Second letters (h, i, j, k, ?):
    • h (8th letter) to i (9th letter): +1 position
    • i (9th letter) to j (10th letter): +1 position
    • j (10th letter) to k (11th letter): +1 position
    • Continuing the pattern, k (11th letter) to the next letter would be l (12th letter).
  3. Third letters (g, f, e, d, ?):
    • g (7th letter) to f (6th letter): -1 position
    • f (6th letter) to e (5th letter): -1 position
    • e (5th letter) to d (4th letter): -1 position
    • Continuing the pattern, d (4th letter) to the next letter would be c (3rd letter).
Thus, the missing term is olc.
The correct answer is B: olc.

Smita rane answered
The given letter series is formed by alternating between the letters in the English alphabet. The first term 'd' is followed by the fourth letter 'e', then the sixth letter 'f', and so on. Similarly, the second term 'j' is followed by the ninth letter 'i', then the eleventh letter 'h', and so on.

To find the missing term, we need to continue the same pattern of alternating between the letters in the English alphabet. The next letter after 'm' is 'n', so the missing term should be the thirteenth letter after 'n', which is 'r'.

Therefore, the missing term in the given letter series is 'prq', which is option (c).

Pallabi Deshpande answered
We can look at the first and second letters separately:
  1. First letter pattern (B, C, ?, H, L):
    • B to C: +1 position
    • C to ?: +2 positions
    • H to L: +4 positions
    • The missing letter should be E (C + 2 = E).
  2. Second letter pattern (F, H, ?, O, T):
    • F to H: +2 positions
    • H to ?: +3 positions
    • O to T: +5 positions
    • The missing letter should be K (H + 3 = K).
Thus, the missing term is EK.
The correct answer is C: EK.

How many such pairs of letters are there in the word FRIENDSHIP, each of which has as many letters between them in the word as in the English alphabet?

  • c)
    Two                            
  • d)
    Three
  • e)
    None of these
Correct answer is option 'D'. Can you explain this answer?

Divisha rane answered
Solution:
To solve this problem, we need to identify pairs of letters in the word FRIENDSHIP that have the same number of letters between them in the word as in the English alphabet. Let's start by listing the English alphabet and the letters in the word FRIENDSHIP:

English Alphabet: 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
FRIENDSHIP: F R I E N D S H I P

Now, we need to identify pairs of letters that have the same number of letters between them in the word as in the English alphabet. For example, the pair "F" and "I" have two letters between them in the word FRIENDSHIP (R and E), and two letters between them in the English alphabet (G and H). Therefore, this pair satisfies the condition.

Using this method, we can identify the following pairs:

• F and I (2 letters between them)
• R and U (2 letters between them)
• E and H (4 letters between them)

Therefore, there are three pairs of letters in the word FRIENDSHIP that satisfy the given condition. The correct answer is option D.

Given series: Q R M ? F D ?

To find: Missing terms in the series

Solution:
The given series consists of alphabets.

Observations:
- The letters are in descending order of their positions in the English alphabet.
- The difference between consecutive letters is not constant.

The missing letters can be found by analyzing the difference between their positions in the alphabet.

Calculation:
- Position of Q in the alphabet = 17
- Position of R in the alphabet = 18
- Difference = 1
- Position of M in the alphabet = 13
- Position of F in the alphabet = 6
- Difference = 7
- The missing letter between M and F should have a position in the alphabet = 13 - 7 = 6
- The letter with a position of 6 in the alphabet is C
- Position of D in the alphabet = 4
- The missing letter between F and D should have a position in the alphabet = 4 + 7 = 11
- The letter with a position of 11 in the alphabet is K

Therefore, the missing terms in the series are C and K.

Verification:
The series becomes: Q R M C F D K
- The difference between Q and R is 1
- The difference between R and M is 5
- The difference between M and C is 7
- The difference between C and F is 3
- The difference between F and D is 7
- The difference between D and K is 6

Conclusion:
The missing terms in the series are C and K, which are present in option D. Hence, the answer is option D.

We can break this down into two alternating patterns:
  1. First pattern (Z, X, T, P, N, ?):
    • Z (26th letter), X (24th letter), T (20th letter), P (16th letter), N (14th letter).
    • The pattern is decreasing by 2, 4, 4, 2 alternately.
    • After N (14th), subtract 4 to get J (10th letter).
  2. Second pattern (Y, U, S, O, K, ?):
    • Y (25th letter), U (21st letter), S (19th letter), O (15th letter), K (11th letter).
    • The pattern is decreasing by 4 each time.
    • After K (11th), subtract 4 to get G (7th letter).
Thus, the missing terms are J and G.
The correct answer is D: J, G.

Dhruv Mehra answered
We can see a clear pattern where letters are decreasing by 1 or 2 positions alternately in the alphabet:
  • W (23rd letter) to V (22nd letter): -1 position.
  • V (22nd letter) to T (20th letter): -2 positions.
  • T (20th letter) to S (19th letter): -1 position.
  • S (19th letter) to Q (17th letter): -2 positions.
  • Q (17th letter) to P (16th letter): -1 position.
  • P (16th letter) to N (14th letter): -2 positions.
  • N (14th letter) to M (13th letter): -1 position.
Following the same alternating pattern:
  • From M (13th letter), subtract 2 positions, which gives K (11th letter).
  • From K (11th letter), subtract 1 position, which gives J (10th letter).
Thus, the missing terms are K and J.
Since none of the provided options match this, the correct answer is D: None of these.

Bayshore Academy answered
We can see that the letters in the series are decreasing by a fixed number of positions in the alphabet. Here's how the pattern works:
  • Y to W: Moving 2 positions back in the alphabet (Y -> X -> W)
  • W to U: Moving 2 positions back (W -> V -> U)
  • U to S: Moving 2 positions back (U -> T -> S)
  • S to Q: Moving 2 positions back (S -> R -> Q)
Following the same pattern, we move 2 positions back from Q:
  • Q to O: (Q -> P -> O)
  • O to M: (O -> N -> M)
Thus, the next two letters in the sequence are O and M.
The correct answer is D: O, M.
