What is the age of Anita now when the square of Anita's age 6 years ago is equal to her age in 6 years time showing work?
Let Anita's age now be x If: (x-6)^2 = x+6 => x^2-12x+36 = x+6 => x^2-13x+30 = 0 Solving the above quadratic equation: x = 3 or x = 10 Therefore Anita's age now must be 10 years of age

2 you are currently 5 times as old as your son In 6 years time you will be three times as old as he will be then What are your ages?
If x is the age of the son, then 5x would be the age of the father. In 6 years, the son would be x + 6 years old, where the father would be 3(x + 6) years old. Since the original age of the father is 5x, then in 6 years the father could also be said to be 5x + 6 years old. Setting these two expressions for the father's age as an equation, we then can solve for x, the son's age. 3(x + 6) = 5x +6 3x + 18 = 5x + 6 2x = 12 x = 6 The original age of the son is 6 and of the father (5x) is 30 years old. In 6 years, the son would be 12 and the father would be [3x + 18 or 5x + 6] 36 years old.
