Question 776905: Let the daughter's age be x
Let the father's age be 4x
3 years ago: Daughter's age = x-3
Father's age = 4x-3
Product of their ages:( x-3)(4x-3)=430
Opening the bracket and applying quadratic formula method, we shall have the roots as x= 12.3 and -8.6
So, taking the positive value of x= 12.3years.
Present ages:
Daughter's (x-3)years = 12.3-3 =9.30years (9 years 3 months)
Father's age: (4x-3)years= 4�12.3-3 = 46.21years (46 years 2 months 1day)
Checking:
9.30�46.21= 429.753 = 430 (approximated)
