You cannot use (e + f) = v^2/127R. It is for super-elevated curves not for horizontal curves.

R = V * V/27.5 = 131 m
So, the answer is A.
So, the answer is A.

If we have to calculate the superelevation for only single vehicle then we use 127 and when we have to calculate superelevation for design speed (for all vehicle which are going to move on curve) we use 225.

If we calculate for signal traffic, we will take 225.

Guys can you tell me where we have to use 127 and where 225?

R = V^2/(e+f)g.

R = v*v/(e+f)*g.

Please tell me formula for this?

e+f = V*V / 127 R.
R = V*V/ 127*(0.07+.15).
R = V*V/ 127*(0.07+.15).

R = 60*60/127(.07+.15) = 128.8.
