Answer 1

Answer:

A. 21 years

Step-by-step explanation:

See as average age of the 6 members is 25 years, then the sum of their ages will be 25*6=150

If a member died one member will get reduced and the sum of their age will also decrease (150 - 45 = 105)

Then the average age of remaining members will be = 105 / 5= 21 years.
