Select an option to attempt

Explanation

To find the reverse letter of each letter in "LUCKNOW," we use a formula similar to finding ranks from the top and bottom:

Letter’s Original Position + Reverse Letter’s Position = $26$ (Total Letters) + $1$ , or $27$ .

Thus, the reverse position of any letter can be found as: Reverse Position = $27$ - Original Position

Now, we apply this formula to each letter in "LUCKNOW":

L: 12th letter → $(27 - 12 = 15)$ , which is O U: 21st letter → $(27 - 21 = 6)$ , which is F C: 3rd letter → $(27 - 3 = 24)$ , which is X K: 11th letter → $(27 - 11 = 16)$ , which is P N: 14th letter → $(27 - 14 = 13)$ , which is M O: 15th letter → $(27 - 15 = 12)$ , which is L W: 23rd letter → $(27 - 23 = 4)$ , which is D
