Solve the problem of Olympic mathematics for primary school students
Because the total age of father and daughter was 49 years old three years ago, the total age of father and daughter this year is 49+3+3=55 years old. As we all know, a father is four times as old as a daughter. If the daughter's age is 1, then the father's age is four years old. Father and daughter ***4+ 1=5 copies, which should be 55 years old and one copy should be: 55/(4+1) =1(years old) ... The age of the daughter's father is 16544.
