    ATQ, Total age of 25 students = 25 ├Ч 15 years = 375 years. New average age after 5 students leave = 14 years. Total age of 20 students = 20 ├Ч 14 years = 280 years. Total age of the 5 students who left = 375 тИТ 280 years = 95 years. Average age of the 5 students who left = 95/5 years = 19 years.
