According to IRC grade compensation is provide if the gradient is steeper than 4% or radius of curvature is less than 305m. Since in the problem radius of curvature is given 300 (<305) we can calculate. The answer is 2.75.

According to IRC, grade flatter than 4% grade compensation is not required.

According to IRC grade compensation is not provided for gradients flatter than 4%.

Gradient of a highway is <4%, so the answer is 3% only, no need to compensate.

Why the value 75/300 is taken?

According to IRC, the grade compensation is not necessary for gradients flatter than 4% and therefore when applying grade competition correction, the gradients need not be eased beyond 4%.
