As per IS 456:2000.
26.5.2.1 - Minimum Reinforcement.
The mild steel reinforcement in either direction in slabs shall not be less than 0.15% of the total cross-sectional area.
However, this value can be reduced to 0.12% when high strength Deformed Bar or welded wire fabric is used.

A) 0.15 percent where plain bars are used, and,
B) 0.12 percent where high yield strength (hot rolled and cold twisted) deformed bars or welded wire fabric are used.

The minimum percentage of reinforcement is 0.15% of the gross area if a mild steel bar is used and 0.12% of the gross area if the HYSD bar is used.

The steel reinforcement may be calculated approximately on the % basis of concrete:
And the value depends on the grade of steel.

Not clear. In this question, which reinforcement is provided but 0.15% for mild steel and 0.12% for HYSD bar.

0.15% is the correct answer. Because the minimum grade of steel used in RCC structure is Fe250.

Ans should be .12 because they don't mention type of bar.
So take min i.e .12%.
So take min i.e .12%.

The minimum reinforcement using mild steel in slab should not be in less.

1) 0.15 % for mild steel and.
2) 0.12 % for other than mild steel.
2) 0.12 % for other than mild steel.

Generally 0.15.
HYSD bars 0.12.
So, the Given answer is right.
HYSD bars 0.12.
So, the Given answer is right.
