Jenny' s current age is twice that of her daughter.
Next year, Jenny’s age will be a perfect square, as will her daughter’s .
How old is Jenny’s daughter this year?
:
Let j = J's present age
Let d = daughters present age
:
"Jenny' s current age is twice that of her daughter." therefore:
j = 2d
:
Next year, Jenny’s age will be a perfect square, as will her daughter’s.
:
There aren't too many perfect squares that could be Jenny's age in one year
25, 36, 49, 64
Jenny's present age has to be even (double daughter's age)
with a little "try & see"
Has to be Jenny's present age is 48, next year 49 a perfect square
then daughters present age is 24, next year 25, a perfect square
:
I don't know of a simple equation that can be used to solve this.
