If HOME is coded as 815135. How can ROAD be written as?

The correct answer is Option (2) → 181514

Writing the code of HOME letter by letter shows that each letter is replaced by its position in the alphabet (A = 1, B = 2, …, Z = 26), and the numbers are written side by side:

• HOME: H = 8, O = 15, M = 13, E = 5, giving 815135, the given code

Applying the same rule to ROAD:

• ROAD: R = 18, O = 15, A = 1, D = 4, giving 181514
