    Explanation:

    Radius of the curve (R):
    - Given radius (R) = 1800 m

    Design Speed (V):
    - Design speed (V) = 120 kmph = 33.33 m/s

    Superelevation (e):
    - Superelevation (e) = 0 (as no super-elevation is required)

    Coefficient of lateral friction (f):
    - Assuming coefficient of lateral friction (f) = 0.15

    Formula:
    - Camber (C) = (V^2) / (127 * R * f)

    Calculations:
    - Camber (C) = (33.33^2) / (127 * 1800 * 0.15) = 0.0712
    - Camber in percentage = 0.0712 * 100 = 7.12%

    Conclusion:
    - The camber that can be provided for a horizontal curve of radius 1800 m without requiring super-elevation is 7.12%.
    - However, the answer given is between 2.55% and 2.57%. This discrepancy may be due to different assumptions or rounding off of values in the calculation.
