If BALL = 211212 and CALL = 311212, then DOLL = ?

The correct option is 4151212.

Step-by-step Explanation:

To find the numerical code for the word DOLL, let us analyze the pattern used for encoding the words BALL and CALL.

We can substitute each letter of the alphabet with its corresponding position number in the English alphabet (A = 1, B = 2, C = 3, D = 4, ..., L = 12, O = 15, etc.).

1. Analyzing the word "BALL":

• B = 2
• A = 1
• L = 12
• L = 12

Combining these positional numbers in order gives: 211212, which matches the given code for BALL.

2. Analyzing the word "CALL":

• C = 3
• A = 1
• L = 12
• L = 12

Combining these positional numbers in order gives: 311212, which matches the given code for CALL.

3. Encoding the word "DOLL":

Using the same rule for DOLL:

• D = 4
• O = 15
• L = 12
• L = 12

Combining these numbers in order gives: 4151212.

Therefore, the code for DOLL is 4151212.
