A reinforced concrete column contains longitudinal steel equal to 1 percent of net cross-sectional area of the column. Assume modular ratio as 10. The loads carried (using the elastic theory) by the longitudinal steel and the net area of concrete, are Ps and Pc respectively. The ratio Ps/Pc expressed as percent is

[A]. 0.1
[B]. 1
[C]. 1.1
[D]. 10

Answer: Option D

1/10 * 100 = 10.

Let c/s area of conc =bd.
Therefore,c/s area of steel = .01bd.
We have, modular ratio=10.
So, ((ps/.01bd)÷(pc/bd)) = 10,
From this,
ps÷pc = .1.
But the question is in percentage. So 10%.
