An RCC short column (with lateral ties) of rectangular cross section of $250 \: mm \times 300 \: mm$ is reinforced with four numbers of $16$ mm diameter longitudinal bars. The grades of steel and concrete are $\text{Fe}415$ and $M20$, respectively. Neglect eccentricity effect. Considering limit state of collapse in compression ($\text{IS }456:2000$), the axial load carrying capacity of the column (in kN, up to one decimal place), is ______

If we use .446fck then answer would be 912 KN (This one is more precise) whereas Ace Academy and others have used .45fck in their solution to calculate to answer which makes it 918 KN

But the official key has given a different answer? Will anyone challange it?
I will definitely challenge this question.

They have given answer considering eccentricity effect. But in question it is clearly mentioned to neglect it.

Hope it works out.
Exactly. It was mentioned not to consider the eccentricity.
