0.55 * fy= 228.25-230 n/mm^2.

Yes, correct Answer. When he given comp stress 190 N/mm2.

Allowable stresses for bars have been standardized by IS-1786 as:

1) Ffor Fe 415 grade, permissible tensile stress = 230 N/mm2 & permissible compressive stress = 190 N/mm2.
2) For Fe 500 grade, permissible tensile stress = 275 N/mm2.
