Problema Solution
A father is four times as old as his daughter. In 8 years, he will be three times as old as she is. How old is the daughter now?
Answer provided by our tutors
let 'f' represent the father's and 'd' represent the daughter's age, then:
f = 4d
f+8 = 3(d+8)
solving this system we have
d=16
f=64
the daughter is 16 and the father is 64
