In a code language, ‘RACE’ is written as ‘VWGA’, and ‘BANK’ is written as ‘FWRG’. How will ‘STEM’ be written in that language?

The correct answer is WPII.

Logic / Pattern:
Each letter in the word is shifted according to an alternating pattern of adding 4 and subtracting 4 based on its alphabetical position (A = 1, B = 2, ..., Z = 26):
• 1st letter: +4
• 2nd letter: -4
• 3rd letter: +4
• 4th letter: -4

Step 1: Check 'RACE' → 'VWGA'
• R (18) + 4 = 22 → V
• A (1) - 4 = 23 → W
• C (3) + 4 = 7 → G
• E (5) - 4 = 1 → A

Step 2: Check 'BANK' → 'FWRG'
• B (2) + 4 = 6 → F
• A (1) - 4 = 23 → W
• N (14) + 4 = 18 → R
• K (11) - 4 = 7 → G

Step 3: Apply the same pattern to 'STEM'
• S (19) + 4 = 23 → W
• T (20) - 4 = 16 → P
• E (5) + 4 = 9 → I
• M (13) - 4 = 9 → I

Thus, STEM is coded as WPII.
