Question

Seans dad is 30 years oder tnan Sean. In four years time, Seans dad will be three times as old as Sean. Write an equation connecting Seans and his dads age in four years time. How old are Sean and his dad now.

Answer 1

Answer: The current age of Sean and his father is 11 and 41 respectively.

Explanation: The ages of the father and son can be calculated by forming linear equations of both the circumtances given in the question.

Let the current age of Sean be x then current age of his father will be = x+30, according to the question.

Let y be Sean's father's present age then y = x+30.

Now, 4 years later, Sean is (x+4)years old and his father is 3 times as old as Sean.

Therefore, y+4 = 3(x+4)

Now let's solve the last equation by taking the value of y from y=x+30

(x+30)+4 = 3(x+4)

x+34 = 3x+12

2x = 22

x = 11

Therefore, Sean's current age is 11 and his father is 41 years old
