Answer:
Father's age- 48
daughter's age- 19
son's age- 16
Explanation:
Given :–
Age of Daughter is 3 more than Son .
Age of Father is three times of the Son .
Sum of the age of Father and the Daughter is 67 .
To Find :–
The ages of Father , Daughter and Son .
Solution :–
Let the age of Daughter , Son and Father be x , y and z Respectively .
According to the First Condition :-
⇒ x = y + 3 -------------(1)
According to the Second Condition :-
⇒ z = 3y -----------(2)
According to the Third Condition :-
⇒ x + z = 67 ------------(3)
Putting z from Equation(2) in Equation(3) :-
⇒ x + 3y = 67
⇒ x = 67 - 3y ------------(4)
Substituting the value of x from Equation(1) and Equation(4) :-
⇒ 67 - 3y = y + 3
⇒ 3y + y = 67 - 3
⇒ 4y = 64
⇒ y = 64/4
⇒ y = 16 years
Putting the value of 'y' in Equation(4) :-
⇒ x = 67 - 3(16)
⇒ x = 67 - 48
⇒ x = 19 years
Putting the value of 'y' in Equation(2) :-
⇒ z = 3(16)
⇒ z = 48 years
∴ The age of Daughter , Son and Father are 19 , 16 and 48 Years Respectively .
