How old is Jennie?

Gracie went for a morning walk and met her old friend Suzie and her daughter Jennie after a long time. Gracie asked Suzie how old is Jennie to which Jennie replied “In two years I will be twice as old as I was three years ago”. How old is Jennie?

Answer 1

let the present age of jennie is 'x' yrs

3 yrs ago, her age was 'x-3' yrs

2 yrs later, her age will be 'x+2' yrs

according to the given condition,

x+2 = 2(x-3)

x+2 = 2x-6

x = 8 yrs

so the present age of jennie is 8 yrs.

Answer 2

Let Jennie present age be x
3 yrs ago, she was of x-3
After 2 yrs, she will be of x+2
ATQ,
x+2 = 2(x-3)
x+2 = 2x-6
2 + 6 = 2x - x
x = 8
Therefore, Jennie's is 8 years old... :)
