Question

The present age of the father is three times than that of his son . After three years the age of the father will be 7 years more than twice the age of the son. What is the present age of son in years?​

Answer 1

Answer:

Let the son's age be x

Then , according to the condition,

father's age =3x+3

3 years later:

Son's age =x+3

Father's age =3x+3+3=3x+6

According to the condition given ,  

3x+6=10+2(x+3)

3x+6= 10+2x+6

x=10

Thus , the son's present age is 10 years and the father's age is  

3x + 3 = 3 * 10 + 3 = 33 years.

Let,Present age of son be x year

•°•present age of father will be 3x years

After three years,son's age will be (x+3)years
