Correct Answer & Explanation
Option B
• The pattern followed is that each letter is replaced by its alphabetical position.
• C is the 3rd letter.
• A is the 1st letter.
• T is the 20th letter.
• So, CAT → 3120.
• Applying the same logic to 'DOG':
• D is the 4th letter.
• O is the 15th letter.
• G is the 7th letter.
• So, DOG → 4157. (Wait, there was a mistake in the options, let me recheck) Ah, the options are 4157, 4158, 457, 458. Let's re-evaluate.
D = 4
O = 15
G = 7
• So, DOG = 4157. Let's recheck the options. Option A is 4157. My apologies for the confusion. The correct answer should be A.
Let's re-evaluate the question and options to ensure correctness.
Question: If 'CAT' is coded as '3120', how is 'DOG' coded?
Options: (A) 4157, (B) 4158, (C) 457, (D) 458
Explanation:
• Each letter is assigned its alphabetical position.
C = 3
A = 1
T = 20
• So, CAT = 3120.
• Applying the same logic to 'DOG':
D = 4
O = 15
G = 7
• So, DOG = 4157.
• Therefore, the correct option is A.
