Q1:

The minimum superelevation in rolling terrain in plains, is limited to

A 4 %

B 5%

C 6%

D 7%

E 10%

ANS:D - 7%

I think one option also should be there that is, we all know minimum superelevation means it indicates about camber.

So for rolling terrain, it should be minimum superelevation of 2%.
