A rectangular RC beam is simply supported over a span of 8m and carries a dead load of 15kN/m (including self-weight) and an imposed load of 8kN/m. The beam is 250mm wide and has an effective depth of 400mm. Grade 30 concrete is to be used.

Determine if the beam should be singly reinforced or doubly reinforced.
