15 Practice MCQs

1. Which letter is 7th to the right of the 14th letter from the left? Options: A) U B) T C) S D) R
   Answer: A) U
   Solution: 14th from left = N; N + 7 = U
   Shortcut: 14 + 7 = 21st letter → U
   Tag: Forward Position

2. Which letter is 5th to the left of the 8th letter from the right? Options: A) H B) G C) I D) J
   Answer: B) G
   Solution: 8th from right = 19th from left (27-8); 19-5 = 14th → N ❌ wait, 27-8=19 → S; S-5 = N ❌ recheck: 8th from right = 19th from left (S); 5th to left of S = 19-5 = 14 → N ❌ options wrong? Wait: 8th from right is 19th from left (S); 5th to left is 14th → N not in options. Correction: 8th from right = 19th from left (S); 5th to left = 14th → N. Options updated: A) H B) G C) I D) J. Correct answer should be N, but since not listed, let’s adjust question to: “Which letter is 5th to the left of the 8th from right?” 8th from right = S (19th); 5th left = 14th → N. Since N not in options, change question to: “Which letter is 6th to the left of 8th from right?” 19-6=13 → M. Still not matching. Better: “Which letter is 5th to the left of 8th from right?” 19-5=14 → N. Replace options: A) N B) M C) O D) P. Answer: A) N.
   Revised:
   Options: A) N B) M C) O D) P
   Answer: A) N
   Shortcut: 27 − 8 = 19; 19 − 5 = 14 → N

   Tag: Cyclic Shift

8. Mirror pair of M? Options: A) N B) O C) P D) Q
   Answer: A) N
   Solution: M=13; mirror = 27-13 = 14 → N
   Shortcut: 27 − position
   Tag: Mirror Pair

9. How many consonants are between D and P? Options: A) 9 B) 10 C) 11 D) 12
   Answer: C) 11
   Solution: D(4) to P(16) → 11 letters; remove vowels E,I,O → 11−3 = 8 ❌ wait: letters between D(4) and P(16) are E,F,G,H,I,J,K,L,M,N,O → 11 letters; vowels E,I,O → 3; consonants = 11−3 = 8. Options need updating.
   Revised options: A) 8 B) 9 C) 10 D) 11
   Answer: A) 8
   Shortcut: (16−4−1) − 3 vowels = 8

10. 9th from left + 9th from right = ? Options: A) 27 B) 26 C) 28 D) 29
    Answer: A) 27
    Solution: 9th left = I(9); 9th right = R(18); 9+18=27
    Shortcut: Always 27 for same nth from both ends
    Tag: Mirror Pair

11. Which letter is 10th to the right of the 18th from the right? Options: A) C B) D C) E D) F
    Answer: B) D
    Solution: 18th right = 9th left (27-18); 9+10 = 19th → S ❌ wait: 18th from right = 9th from left (I); 10th to right of I is 19th → S. Options wrong.
    Revised: Options: A) S B) T C) R D) Q
    Answer: A) S
    Shortcut: 27 − 18 = 9; 9 + 10 = 19 → S

15. If alphabet is written backwards, which is 5th letter to the left of 12th from right? Options: A) H B) I C) J D) K
    Answer: C) J
    Solution: Backwards: Z,Y,X…; 12th from right in backwards = 12th from left original → L; 5th left of L = 12−5 = 7th original → G ❌ wait: backwards order: Z(1),Y(2)…A(26). 12th from right in backwards = 15th from left backwards = 15th from right original → 12th from left original → L. 5th to left of L in backwards: L is 15th backwards; 5th left = 20th backwards → 7th original → G. Options need updating.
    Revised: Options: A) G B) H C) I D) J
