It's not 300m it is 3000 m above MSL.

Anybody please explain.

Cross slope of country for mountainous terrain is 25-60%,
So, 300*(1/60).

It is 6% for rulling gradient.

Ruling gradient for mountains region 1 in 20 i.e.5%.

Yes, It's not 300m it is 3000 m above MSL,

1. If MSL < 3000 m then ruling gradient 5%.
2. If MSL >3000 m then ruling gradient 6%.

So, the answer is 6%.

MSL given 300 m , If MSL < 3000m rulling gradient 5%.

Steep terrain up to 3000m height above M.S.L.
For;
Ruling gradient -6%.
Limiting grdn-7%.
Exceptional grdn-8%.

Thanks @Sudipta.

I think it should be 3000m MSL, and correct Answer is 5%. For terrain more than 3k, 5% and for less than 3k it should be 6%. It is because of breathing issues above 3k MSL so gradient need to be designed a bit flat.
