Math 2017 Question 25
Question 25
Jada is 9 years old. The sum of her parents’ ages is the square of Jada’s age. Her father is 11 years older than her mother.
How old is Jada’s mother? (3 marks)
Answer
Jada’s Mother’s age = 35
Explanation
Square of Jada’s age: 9×9 = 81
Take away the father’s additional years : 81-11 = 70
Divide the answer to get Jada’s mother age: 70÷2 = 35
The Father’s age: 35 + 11 = 46
Test the addition of the ages: 35+46 = 81
