Answer 2

Answer:

20 years

Step-by-step explanation:

Given :-

• Age of father is 40 years
• Age of son is 10 years

To find :-

The number of years after when the father's age will be twice the son's age.

Solution :-

Let the number of years required be x.

After the required number of years,

age of son will be, 10 + x years

age of father will be, 40 + x years

According to question,

40 + x = 2 × (10 + x)

40 + x = 20 + 2x

2x - x = 40 - 20

x = 20 years

Thus, after 20 years, father's age will be twice of son's age.
