GATE 2016 CE (CE1) – Question 45
A reinforced concrete (RC) beam with width of 250 mm and effective depth of 400 mm is reinforced with Fe415 steel. As per the provisions of IS 456-2000, the minimum and maximum amount of tensile reinforcement (expressed in mm2) for the section are, respectively

Show answer and explanation
Correct answer: (B) 205 and 4000
Explanation
The minimum tension area is0.85bd/fy=0.85·250·400/415=204.82mm², approximately205mm². The maximum is4% of the gross section bD; the keyed option uses4000mm² by taking D=400mm. Thus **B** is retained, but the stem provides effective depth d rather than overall depth D, so the maximum requires that implicit identification.
