Answer 1

Answer:

the average age of members of a 4 member family is 15 years.20 YEARS FROM NOW the average age would be 20 years

Step-by-step explanation:

To get the average age of the family in 20 years, we need to get the sum of their ages now.

The sum of their ages now is given as:

We have four members in the family, and their average age is 15 years.

The sum of their age = 4 × 15 = 60 years

In 20 years, the sum of their ages will be: 60 + 20 = 80 years.

Their age average in 20 years time will be = 80/4 = 20 years
