1. 153.75 mm²
2. 205 mm²
3. 102.5 mm²
4. 41 mm²

Answer 1

Correct Answer - Option 1 : 153.75 mm²

Concept: -

As per IS 456 : 2000, Annex D, Cl. D-1.8,

The area of reinforcement in each of the corner shall be 3 / 4^th of the area required for the maximum mid span moment in the slab spanning in two directions.

Solution: -

The area of steel required at the corner = 3 / 4 × 205 = 153.75 mm².
