SOURCE: Father is 3 times as
So the father is 3 times as old as his daughter.
Let F represent the age of the fatherLet D represet the age of the daughter
So we know from the first sentence,
F = 3 * D
From the second sentence, 12 years from now the father is 1 year les than twice his daughters age,
First, lets assume it's not 12 years from now (to avoid confusion), we would haveF + 1= 2 * D
But since its 12 years from now, we have to add 12 to both ages
(F + 12) + 1 = 2 * (D + 12)
Let's simplify a bit,
F + 13 = 2 * D + 24F = 2D + 11
Now we have to solve these two equations together, we can plug the first equation into the second,
F = 3 * DF = 2 * D + 11
3 * D = 2 * D + 11D = 11
So the daughter is 11 years old, we can find out how old the father is by plugging into the first equation
F = 3 * DF = 3 * 11F = 33
So the father is 33 and the daughter is 11.
