If in a code CAT=3120, then DOG=4157, then BAT=?
2120
2130
3121
2121
2120
The code represents the alphabet positions of each letter in the word written sequentially: C=3, A=1, T=20 -> 3120.
The code represents the alphabet positions of each letter in the word written sequentially: C=3, A=1, T=20 -> 3120.
Analyze the pattern for CAT
C is the 3rd letter, A is the 1st letter, T is the 20th letter. Concatenating these yields 3, 1, 20 which results in 3120.
Verify the pattern for DOG
D is the 4th letter, O is the 15th letter, G is the 7th letter. Concatenating these yields 4, 15, 7 which results in 4157.
Apply the pattern to BAT
B is the 2nd letter, A is the 1st letter, T is the 20th letter. Concatenating these yields 2, 1, 20 which results in 2120.
B: 2130 is incorrect because T is 20, not 30. C: 3121 is incorrect because B is 2, not 3. D: 2121 is incorrect because T is 20, not 21.
A is correct because applying the direct alphabet position mapping (B=2, A=1, T=20) results in the code 2120.
Always write out the numerical positions (A=1...Z=26) immediately when you see letter-to-number codes in reasoning exams.
