Q1:

The relationship between the length (l) and radius (r) of an ideal transition curve is given by

A l ∝ r

B l ∝ r2

C l ∝ 1/r

D l ∝ 1/r2

ANS:C - l ∝ 1/r

Length of transition curve is L = (v^3)/(c*R).

Where R = radius of curve,
From this we can say that L is inversely proportional to Radius of curve.
