@Ranjan Patra.
Where the 10 comes from?

Side dimension is 60.
So, the distance from center within which if load is applied than column does not go under the tension i.e. b/6 = 60/6 = 10, which give the value 10.
As per right angle tringle, you get the side of core that is 14.14.

For a rectangular column, kernel core is a rhombus with diagonals B/3 & D/3 resp.
In the above Question, dimensions of the core are asked in terms of SIDE.
So, to apply Pythagoras theorem, we must consider a quarter of the rhombus, i.e., a triangle which has the sides B/6 & D/6
So, the side of the rhombus = hypotenuse of the triangle = sq root (10^2 + 10^2) = sq root(200) = 14.14

The shape of the core for the square column is square, not a rhombus.
so, ans is b/6 i.e. 60/3=20.
so, ans is b/6 i.e. 60/3=20.

Kern of a square section is also a square so the sides are b/3 & b/3 hence the answer should be 60/3= 20.
If it is a rectangle of 60x60 then the above-given approach is correct.
