Question from Abigail: David Is 6 years older than his sister Delia. In 10 years the sum of There age 52. how old are David and Delia today |
Hi Abigail,
In 10 years from today David will still be 6 years older than Delia. Thus, at that time Delia's age will be her age today plus 10 years and David's age will be Delia's age today plus 6 plus 10 years. The sum of their ages in 10 years is 52 years. What is Delia's age today?
Make sure you verify your answer,
Penny
