2. What became of Chandragupta?

Chandragupta probably abdicated, became an ascetic, accompanied Bhadrabahu to Karnataka and later died by following the ritual of sallekhana, i. e., fasting till death. Chandragupta thus ruled for 24 years and was succeeded by his son Bindusara (297 - c. 273 BCE), father of Ashoka the Great (268-232 BCE)
