I think superelevation = v^2/127r.

e = V^2/gR.
V = 75% of design speed.
V = 0.75*75.
v = V/3.2.
V = 75% of design speed.
V = 0.75*75.
v = V/3.2.

Right it is not declared but the term curve seems something to be the given figure 1000 is the radius.

But it is not declared that 1000 m is the radius of the curve.

e = V^2/225R.
= 75 * 75/(225*1000).
= 1/40 (or).
= 1 in 40.
= 75 * 75/(225*1000).
= 1/40 (or).
= 1 in 40.
