On hills, the max value of super elevation is adopted which is v2/225R.

e+f = v2/127R.
e= v2/225R ( if you ignore friction then take 0.75 of design speed as speed).
e= v2/225R ( if you ignore friction then take 0.75 of design speed as speed).

B is correct because v is design speed(0.75v).

I think B is the answer that formula itself used for V in kmph.

For Kmph, the answer is C.

I think B is the correct answer.

It is V^2/127R.

As per IRC 52, the correct answer is C.

C is the correct answer as e+u=V^2/(127R) but if we calculate e only without the coefficient of friction formula is e=(0.75V)2/(127R) ie V^2/(225R).

The Correct answer is options B i.e. e = v^2/(127R).
