1. The pile is suspended at one point, max moment = wL^2/28.
2. The pile is suspended at two-point, max moment = wL^2/47.
3. The pile is suspended at three-point, max moment = wL^2/90.

The pile suspended in three points at 0.15L from two ends and in the middle of the beam 0.5L.
From 0L to 0.15L the beam is overhanging and also from 0.85L to L.

The overhanging beam have hogging moment,

= 0.15WL*(0.15/2) * L = 0.01125 = WL2/90.

Can anyone explain the solution clearly?

Pile suspended at one point, max moment = wL^2/8.

Pile suspended at two points, Max Moment = wL^2/47.
Pile suspended at three points, max Moment = wL^2/90.

When the pile is suspended at three points, the max bending moment is =wL^2/90.

In this case , the bending moment will be least when the end point are located at a distance of 0.15L from the corresponding ends. (Applied this vice versa).

How the problem solve?
