As per IRC grade compensation is not necessary for gradient flatter than 4%.
Hence option E is the right answer.
Hence option E is the right answer.

I think there is no grade compensation.

The maximum grade compensation =75/R.
Given R=300m.
Now grade compensation is = 75/300.
which is =2.5.
So, option D is correct.

Now grade compensation is = 75/300.

So, option D is correct.

Grade compensation =75/R%.
75/300= 0.25.
Then given ruling gradient is 3%.
3 - 0.25= 2.75 %.
75/300= 0.25.
Then given ruling gradient is 3%.
3 - 0.25= 2.75 %.

@All.
There is a rule that if the calculated gradient comes less than 4%, then we can't provide it. Hence the minimum compensated gradient value is 4%.

As per IRC no compensation will be done to the gradient flatter than 4%.
So, the answer should be 3%.
So, the answer should be 3%.

If the curve provided is <40 then use the formula 30+R/ 30.
And if curve>40 then use the formula 75/R.
Here we use the latter one;
Now, 75/300 = 0.25.
Compensated G= 3-0.25 = 2.5.
And if curve>40 then use the formula 75/R.
Here we use the latter one;
Now, 75/300 = 0.25.
Compensated G= 3-0.25 = 2.5.

3 - (75/300) = 2.75.

The answer should be 3% because it is already flatter than 4%.
As per IRC no GC for less than 4%.
Although as per calculation by formula it is coming out to be 2.75%.
{(30+R)/R OR 75/R}MIN VALUE ADOPTED.
