Manuscript of ever-changing jokes

The insect apple patrolled his manor and went to the pasture. He saw a herdsman driving a flock of sheep on the grass, and another herdsman followed him with a fat sheep. The worm apple asked the herder in front, "Do you have 100 sheep?" Herdsmen said, "If there are such sheep, plus semigroups, there will be a quarter of the sheep, plus 1, there will be 100 colored sheep." Do you know how many?

Answer: (100-1)/(1+1+2+1/4) = 36 (only)
