Question

Erica is five years younger than Rose .Four year later, Rose will be twice as old as Ella .Find their present ages

Answer 1

Answer:

Let the present age of Rose be x.

then Ella's age=x-5

4 years later,

Age of Rose= x+4

Age of Ella=x-5+4=x-1

According to the question,

x+4=2(x-1)

x+4=2x-2

⇒4+2=2x-x

⇒x=6

∴present age of Rose=6 years

preasent age of Ella=6-5=1 year
