Q1:

If the dimensions of a rectangular section of a short column are 15 cm x 20 cm, its unsupported length should be restricted to

A 9.0 m

B 10.0 m

C 11.0 m

D 12.0 m

ANS:A - 9.0 m

Refer IS 456.

Clause 25.3(Slenderness limit of columns)
25.3.1 say that,

The unsupported length between end restraints shall not exceed 60 times the least lateral dimension of a column.
So as per is standard
60 * 1.5 = 9 m.

I hope all clear.
