Step-by-step explanation:

Given that:A father says to his son, 7 years ago I was 7 times as old as

you were and after 3 years I will

the 3 times as old as you

will be.

To find: present ages of son and father

Solution: Let the present age of father is x years

Son's present age is y years

7 years ago,age of father is (x-7) years

and Son's age is (y-7) years

(x-7)=7(y-7)

x-7y=-49+7

x-7y=-42 ...eq1

After three years age of father will be (x+3) years and Son's age will be (y+3) years

Now,ATQ

(x+3)=3(y+3)

x-3y=6...eq2

Subtract both eq1 and eq2

x-7y=-42

x-3y=6

(-) (+) (-)

-------

-4y=-48

y=48/4

y=12 years

Now put the value of y in eq2

x-3×12=6

x=6+36

x=42 years

Thus,

The present age of father is 42 years

Son's present age is 12 years.

Hope it helps you.
