r>300 only extra widening is provided.

Ng Reddy said: (Sep 28, 2016)  
r > 300 there is no need extra widening.

Anshu said: (Nov 23, 2016)  
150 < 300 so extra widening is provided.

Bappa said: (Feb 11, 2017)  
As the radius 150 less than 300m, so widening of curves provide by.0.6m (when r=101 to 300) for two lane. So given answer is wrong.

Extra widening of single lane pavements is 'Nil' for radius 101 to 300.

Roy said: (Oct 24, 2017)  
Provision of extra widening is nil, for a single lane of radius greater than 60m and for two-lane greater than 300 m.

Madhu said: (Dec 29, 2017)  
For single lane road r>100 , extra widening=0
For double lane road r>300, extra widening=0

In question, they have not mentioned whether it is a single lane or double lane road. so the question is contradictory.

As this is a hill roads no extra widening is provided.

FOR SINGLE LANE ROAD R>100 Ew=0.
FOR TWO LANE ROAD R>300 Ew=0.

Manish said: (Sep 6, 2019)  
150 lies between 5>R>300, so EW provide in both side.

Anirban Roy said: (Aug 24, 2020)  
For 1 lane road if R>60--> Ew= 0.
For 2 lane road if R>300--> Ew= 0.
