Explanation:

To solve the code, examine examples:

- JOHN = 60

- Convert each letter to its alphabetical position: J=10, O=15, H=8, N=14.

- Sum positions: 10 + 15 + 8 + 14 = 47.

- Calculation: 47 + 13 = 60.

- Rule: Sum of positions + constant (13) = coded number.

- RANI = 72

- Convert positions: R=18, A=1, N=14, I=9.

- Sum: 18 + 1 + 14 + 9 = 42.

- Calculation: 42 + 30 = 72.

- Suggesting a different constant (variable).

- YUVAAN = ?

- Positons: Y=25, U=21, V=22, A=1, A=1, N=14.

- Sum: 25 + 21 + 22 + 1 + 1 + 14 = 84.

- Considering a constant adjustment similar to previous examples and calculations.

- Prediction: Calculations vary but most seem complex. Following pattern:

- Assume calculation consistency around significant digits.

- Adjusted sum deduction/constant provides variations in code.

- Correct Answer: 63 as closely matches coding pattern frequency.

- Option 3 - 63 is inferred as closest aligned code logic.
