37.
If D is the diameter of a circular sewer and D' is the top horizontal diameter of an equivalent egg shaped section, the relationship which holds good, is
D' = 0.64 D
D' = 0.74 D
D' = 0.84 D
D' = 0.94 D.

Area of circular sewer = pi/4 * D^2.
Area of egg-shaped sewer = (15+8*π)/32 * D'^2.
Equate them.
