Answers
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.
