Answer:

The answer to the given question is the sum of the ages of four friends after 3 years will be

$x + 12$

Step-by-step explanation:

Given :

the sum of the present ages of 4 friends is 'x' year's

To find

The sum of their ages after 3 years.

Solution :

The sum of the ages of four friends is x.

when the years go the ages of people will also increase.

Every year the age of a person will increase by 1.

Then for three years, the age will be increased by 3 for each person.

The age will be obtained by multiplying the 4 friends by the 3 and adding it to the present ages.

The sum of their ages after 3 years =

$x + (3 \times 4) \\ x + 12$

Hence, the age of the four friends after three years will be x+12.

Therefore, the final answer will be

$x + 12$
