In a certain code language, ‘DICE’ is written as ‘EKFI’ and ‘PLAN’ is written as ‘QNDR’.
How will ‘LUDO’ be written in that language?

The correct answer is MWGS.

Step-by-Step Explanation:

To find how 'LUDO' is written in this code language, let's analyze the relationship between the original words and their coded forms by looking at the alphabetical position of each letter.

1. Analyzing 'DICE' → 'EKFI':
• D (4^th letter) + 1 = E (5^th letter)
• I (9^th letter) + 2 = K (11^th letter)
• C (3^rd letter) + 3 = F (6^th letter)
• E (5^th letter) + 4 = I (9^th letter)
The rule applied here is adding +1, +2, +3, and +4 sequentially to the positions of the letters.

2. Verifying with 'PLAN' → 'QNDR':
• P (16^th letter) + 1 = Q (17^th letter)
• L (12^th letter) + 2 = N (14^th letter)
• A (1^st letter) + 3 = D (4^th letter)
• N (14^th letter) + 4 = R (18^th letter)
The pattern of adding +1, +2, +3, and +4 is confirmed.

3. Applying the same pattern to 'LUDO':
• L (12^th letter) + 1 = M (13^th letter)
• U (21^st letter) + 2 = W (23^rd letter)
• D (4^th letter) + 3 = G (7^th letter)
• O (15^th letter) + 4 = S (19^th letter)

Hence, 'LUDO' is written as MWGS.
