Answer:
175 years
Step-by-step explanation:
YPLL is years of potential life lost. Represents number of years a person would have lived if they didn't die early.
To calculate the YPLL use the following formula
YPLL= Σ(age at endpoint - age of death)
YPLL= (65-20)+(65-25)+(65-30)+(65-35)+(65-40)
YPLL= 45+ 40+ 35+ 30+ 25
YPLL= 175 years
