In a certain code language, ‘CITY’ is written as ‘241872’, and ‘DRUG’ is written as ‘239620’. How will ‘GOLF’ be written in that language?

The correct option is 20121521.

Logic/Pattern:
Each letter of the word is coded using the positional rank of its reverse alphabetical counterpart (opposite letter). The position of the opposite letter in the English alphabet can be calculated by subtracting the standard position of the letter from 27.

Let us verify the pattern with the given example words:

For 'CITY':

• C (3rd letter) ⇒ $27-3=24$

• I (9th letter) ⇒ $27-9=18$

• T (20th letter) ⇒ $27-20=7$

• Y (25th letter) ⇒ $27-25=2$

Concatenating these values gives: 241872.

For 'DRUG':

• D (4th letter) ⇒ $27-4=23$

• R (18th letter) ⇒ $27-18=9$

• U (21st letter) ⇒ $27-21=6$

• G (7th letter) ⇒ $27-7=20$

Concatenating these values gives: 239620.

Now, applying the exact same pattern to 'GOLF':

• G (7th letter) ⇒ $27-7=20$

• O (15th letter) ⇒ $27-15=12$

• L (12th letter) ⇒ $27-12=15$

• F (6th letter) ⇒ $27-6=21$

Concatenating the calculated values gives: 20121521.
