In the English alphabet, the first 4 letters are written in opposite order; and the next 4 letters are written in opposite order and so on; and at the end Y and Z are interchanged. Which will be the fourth letter to the right of the 13th letter?
- A.N
- B.T
- C.H
- D.I
▶ Answer & Explanation
Correct answer: B. T
The question describes a specific rearrangement of the English alphabet. The first 4 letters (ABCD) are reversed to DCBA. The next 4 letters (EFGH) are reversed to HGFE, and this pattern continues. Y and Z are interchanged. To find the 13th letter's position after this rearrangement, we must determine how the reversal pattern affects the 13th position and then count four letters to its right in the new sequence.
