If slenderness ratio is lies between 12 - 60 then its short column. For greater than 60 it long or slender column.

LNG column is l/b greater than 12 or l/r greater than 40.

The unsupported length between end restraints shall not exceed 60 times the least lateral dimension of a column.

Please explain why answer 50?

If Leff/LLD >12 then it is a long column.

Everyone is confused with slenderness ratio and ratio of effective length to least lateral dimension.
You should know that both are not same. Slenderness ratio is the ratio of effective length to the radius of gyration.

Long column (l/b) > 12 or (l/r) > 40.
Where,
l = Effective length.
r = Radius of gyration.
b = Least dimension.
l/r is slenderness ration and it should be > 40. So 50 is the answer.

I think this answer is wrong.
If slenderness ratio is >12 then it is long column & <12 is short column.
If slenderness ratio is >12 then it is long column & <12 is short column.

Because the slenderness ratio related with constant 12 is for RCC column and 40 is for steel column.

L/b < 12 then short column.
L/b > 12 then long column.
When l/b = 12, then what is it?
L/b > 12 then long column.
When l/b = 12, then what is it?
