Q:

# 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

Explanation:

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 $\inline \alpha$ and  $\inline \beta$respectively.Then,

The required letter = $\inline 2\alpha +\beta +1 - required \: position \: of\: letter\: from \: the\: left$

Therefore, The required letter = 26 + 13 + 1 - 18 = 22 = V
