Elastic , Inelastic and Perfectly inelastic collions

Questions based on elastic , inelastic and perfectly inelastic collsion

In inelastic collision,

Statement-1 : Kinetic energy is conserved in both, perfectly elastic and perfectly inelastic collisions. Statement-2 : Because linear momentum is conserved in both.

For a perfectly elastic collision and a perfectly inelastic collision, values of coefficient of restitution are respectively

Is whol of the kinetic energy lost in any perfectly inelastic collision?
