Q. If ‘ZERO’ is written as ‘CHUR’, then how is ‘PLAYER’ written?

Explanation : 

Decoding ‘PLAYER’ based on pattern from ‘ZERO’ to ‘CHUR’

Each letter in the word “ZERO” is replaced by the letter that is three places ahead of it in the English alphabet.

Z -> C (Z is the 26th letter, C is the 3rd letter, 26+3 = 29, but since there are only 26 letters, we subtract 26 to get 3)
E -> H (E is the 5th letter, H is the 8th letter, 5+3 = 8)
R -> U (R is the 18th letter, U is the 21st letter, 18+3 = 21)
O -> R (O is the 15th letter, R is the 18th letter, 15+3 = 18)

So, using the same rule for “PLAYER”:

P -> S (P is the 16th letter, S is the 19th letter, 16+3 = 19)
L -> O (L is the 12th letter, O is the 15th letter, 12+3 = 15)
A -> D (A is the 1st letter, D is the 4th letter, 1+3 = 4)
Y -> B (Y is the 25th letter, B is the 2nd letter, 25+3 = 28, but since there are only 26 letters, we subtract 26 to get 2)
E -> H (E is the 5th letter, H is the 8th letter, 5+3 = 8)
R -> U (R is the 18th letter, U is the 21st letter, 18+3 = 21)

So “PLAYER” is written as “SODBHU”.
