Public bug reported:

Binary package hint: gbrainy

V1.51

Q:
Out of 40 people, 13 have brothers, 14 have sisters and 8 have both. How many people have neither brothers nor sisters.

A:
The correct answer is 21.5 people have brothers only, 6 sisters only and 8 have sisters and brothers.

Is there a half brother somewhere?  I would guess by the wording, that
the 8 that have both would be part of the 27 that have one or the other.
That would be 13 that have neither.  If the wording is unclear, and the
13 and 14 are exclusive, and only have brother, or only have sister,
then the 8 would be in addition to the 27.  Which would be 35, leaving 5
with neither.  So it looks like a bug to me.
